The quadratic formula

In basic algebra, the quadratic formula is the solution of the quadratic equation. There are other ways to solve the quadratic equation instead of using the quadratic formula, such as factoring, completing the square, or graphing. However, using the quadratic formula is often the most convenient way.

The general quadratic equation is

Here x represents an unknown, and a, b, and c are constants with a not equal to 0. One can easily verify that the quadratic formula satisfies the quadratic equation, by inserting the former into the latter. Each of the solutions given by the quadratic formula is called a root of the quadratic equation.

Derivation of the formula

Once a student understands how to complete the square, then he or she can derive the quadratic formula.[1][2] For that reason, the derivation is sometimes left as an exercise for the student, who can thereby experience rediscovery of this important formula.[3][4] The explicit derivation is as follows.

Divide the quadratic equation by a, which is allowed because a is non-zero:

Subtract c/a from both sides of the equation, transforming it into the form

One way to think of this derivation is in geometric terms. Lengths are in green, and area is in red.

The quadratic equation is now in a form to which the method of completing the square can be applied. To "complete the square", add a constant to both sides of the equation such that the left hand side becomes a complete square:

which produces

or (after rearranging the terms on the right hand side to have a common denominator)

The square has thus been completed, as shown in the figure. Taking the square root of both sides yields

Isolating x gives the quadratic formula:

The plus-minus symbol "±" indicates that both

are solutions of the quadratic equation.[5] There are many alternatives of this derivation with minor differences, mostly concerning the manipulation of .

Some sources, particularly older ones, use alternative parameterizations of the quadratic equation such as [6] or ,[7] where b has a magnitude one half of the more common one. These result in slightly different forms for the solution, but are otherwise equivalent.

Historical development

Brahmagupta described the quadratic formula more clearly than anyone had done before.

The Indian mathematician Brahmagupta (597–668 AD) was first to clearly describe the quadratic formula, although prior civilizations had investigated quadratic equations, understood them fairly well, and developed methods for solving them.[8] Brahmagupta's formula was written in words, instead of symbols, in his treatise Brāhmasphuṭasiddhānta published in 628 AD.[9] His solution of the quadratic equation was as follows:

To the absolute number multiplied by four times the [coefficient of the] square, add the square of the [coefficient of the] middle term; the square root of the same, less the [coefficient of the] middle term, being divided by twice the [coefficient of the] square is the value. (Brahmasphutasiddhanta, Colebrook translation, 1817, page 346.)[10]

This is equivalent to:

Mathematics Professor Elizabeth Stapel has explained what motivated the discovery of this formula:[11]

Somebody (possibly in seventh-century India) was solving a lot of quadratic equations by completing the square. At some point, he noticed that he was always doing the exact same steps in the exact same order for every equation. Taking advantage of one of the great powers and benefits of algebra (namely, the ability to deal with abstractions, rather than having to muck about with the numbers every single time), he made a formula out of what he'd been doing....

The quadratic formula covering all cases was first obtained by Simon Stevin in 1594.[12] In 1637 René Descartes published La Géométrie containing the quadratic formula in the form we know today. The first appearance of the general solution in the modern mathematical literature appeared in an 1896 paper by Henry Heaton.[13]

Importance of this solution

Among the many equations that one encounters while studying algebra, the quadratic formula is one of the most important, and is considered the most useful method of solving quadratic equations.[14][15] Unlike some other solution methods such as factoring, the quadratic formula can be used to solve any quadratic equation.[16][17] Many equations that are not naively quadratic can be put into quadratic form, and solved using the quadratic formula.[18] For these reasons, it is often memorized.[19][20]

Completing the square also allows for the solution of all quadratics, as it is mathematically equivalent to the quadratic formula, but the quadratic formula gives a result without the need for so much algebraic manipulation. As such it is generally considered more practical to use the formula.[17][21][22][23] However, completing the square is very useful for other purposes, such as putting the equations for conic sections into standard form.[24]

Other derivations

A number of alternative derivations of the quadratic formula can be found in the literature which either (a) are simpler than the standard completing the square method, (b) represent interesting applications of other frequently used techniques in algebra, or (c) offer insight into other areas of mathematics.

Alternate method of completing the square

The great majority of algebra texts published over the last several decades teach completing the square using the sequence presented earlier: (1) divide each side by a, (2) rearrange, (3) then add the square of one-half of b/a.

However, as pointed out by Larry Hoehn in 1975, completing the square can be accomplished by a different sequence that leads to a simpler sequence of intermediate terms: (1) multiply each side by 4a, (2) rearrange, (3) then add .[25]

In other words, the quadratic formula can be derived as follows:

This actually represents an ancient derivation of the quadratic formula, and was known to the Hindus at least as far back as 1025 A.D.[26] Compared with the derivation in standard usage, this alternate derivation is shorter, involves fewer computations with literal coefficients, avoids fractions until the last step, has simpler expressions, and uses simpler math. As Hoehn states, "it is easier 'to add the square of b' than it is 'to add the square of half the coefficient of the x term'".[25]

By substitution

With this technique, we substitute into the quadratic to get:

Expanding the result and then collecting the powers of produces:

We have not yet imposed a second condition on and , so we now choose m so that the middle term vanishes. That is, or . Subtracting the constant term from both sides of the equation (to move it to the right hand side) and then dividing by a gives:

Substituting for gives:

Therefore ; substituting provides the quadratic formula.

By using algebraic identities

Let the roots of the standard quadratic equation be and . At this point, we recall the identity:

Taking square root on both sides, we get

We know that the sum of roots of the standard quadratic equation is given by :

Additionally, the product is given by :

Hence the identity can be rewritten as:

Now,

An alternative way of deriving the quadratic formula is via the method of Lagrange resolvents, which is an early part of Galois theory.[27] This method can be generalized to give the roots of cubic polynomials and quartic polynomials, and leads to Galois theory, which allows one to understand the solution of algebraic equations of any degree in terms of the symmetry group of their roots, the Galois group.

This approach focuses on the roots more than on rearranging the original equation. Given a monic quadratic polynomial

assume that it factors as

Expanding yields

where and .

Since the order of multiplication does not matter, one can switch and and the values of p and q will not change: one says that p and q are symmetric polynomials in and . In fact, they are the elementary symmetric polynomials – any symmetric polynomial in and can be expressed in terms of and The Galois theory approach to analyzing and solving polynomials is: given the coefficients of a polynomial, which are symmetric functions in the roots, can one "break the symmetry" and recover the roots? Thus solving a polynomial of degree n is related to the ways of rearranging ("permuting") n terms, which is called the symmetric group on n letters, and denoted For the quadratic polynomial, the only way to rearrange two terms is to swap them ("transpose" them), and thus solving a quadratic polynomial is simple.

To find the roots and consider their sum and difference:

These are called the Lagrange resolvents of the polynomial; notice that one of these depends on the order of the roots, which is the key point. One can recover the roots from the resolvents by inverting the above equations:

Thus, solving for the resolvents gives the original roots.

Formally, the resolvents are called the discrete Fourier transform (DFT) of order 2, and the transform can be expressed by the matrix with inverse matrix The transform matrix is also called the DFT matrix or Vandermonde matrix.

Now is a symmetric function in and so it can be expressed in terms of p and q, and in fact as noted above. But is not symmetric, since switching and yields (formally, this is termed a group action of the symmetric group of the roots). Since is not symmetric, it cannot be expressed in terms of the polynomials p and q, as these are symmetric in the roots and thus so is any polynomial expression involving them. However, changing the order of the roots only changes by a factor of and thus the square is symmetric in the roots, and thus expressible in terms of p and q. Using the equation

yields

and thus

If one takes the positive root, breaking symmetry, one obtains:

and thus

Thus the roots are

which is the quadratic formula. Substituting yields the usual form for when a quadratic is not monic. The resolvents can be recognized as being the vertex, and is the discriminant (of a monic polynomial).

A similar but more complicated method works for cubic equations, where one has three resolvents and a quadratic equation (the "resolving polynomial") relating and which one can solve by the quadratic equation, and similarly for a quartic (degree 4) equation, whose resolving polynomial is a cubic, which can in turn be solved. However, the same method for a quintic equation yields a polynomial of degree 24, which does not simplify the problem, and in fact solutions to quintic equations in general cannot be expressed using only roots.
