A polynomial in one variable i. The individual summands with the coefficients usually included are called monomials Becker and Weispfenningp.

However, the term "monomial" is sometimes also used to mean polynomial summands without their coefficients, and in some older works, the definitions of monomial and term are reversed. Care is therefore needed in attempting to distinguish these conflicting usages. The highest power in a univariate polynomial is called its orderor sometimes its degree.

Any polynomial with can be expressed as. A polynomial in two variables i. The sum of two polynomials is obtained by adding together the coefficients sharing the same powers of variables i. Similarly, the product of two polynomials is obtained by multiplying term by term and combining the results, for example. The process of performing such a division is called long divisionwith synthetic division being a simplified method of recording the division.

For any polynomialdividesmeaning that the polynomial quotient is a rational polynomial or, in the case of an integer polynomialanother integer polynomial N. Sato, pers. Exchanging the coefficients of a univariate polynomial end-to-end produces a polynomial. Horner's rule provides a computationally efficient method of forming a polynomial from a list of its coefficients, and can be implemented in the Wolfram Language as follows. Polynomials of fourth degree may be computed using three multiplications and five additions if a few quantities are calculated first Press et al.

Similarly, a polynomial of fifth degree may be computed with four multiplications and five additions, and a polynomial of sixth degree may be computed with four multiplications and seven additions. Polynomials of orders one to four are solvable using only rational operations and finite root extractions. A first-order equation is trivially solvable. A second-order equation is soluble using the quadratic equation. A third-order equation is solvable using the cubic equation.

A fourth-order equation is solvable using the quartic equation. It was proved by Abel and Galois using group theory that general equations of fifth and higher order cannot be solved rationally with finite root extractions Abel's impossibility theorem.

However, solutions of the general quintic equation may be given in terms of Jacobi theta functions or hypergeometric functions in one variable.

Hermite and Kronecker proved that higher order polynomials are not soluble in the same manner. Klein showed that the work of Hermite was implicit in the group properties of the icosahedron. Klein's method of solving the quintic in terms of hypergeometric functions in one variable can be extended to the sextic, but for higher order polynomials, either hypergeometric functions in several variables or "Siegel functions" must be used BelardinelliKingChow These functions turned out to be "natural" generalizations of the elliptic functions.Make the polynomial have zero derivative at and without specifying the values there:.

To avoid ambiguous queries, make sure to use parentheses where necessary. Here are some examples illustrating how to ask about factoring.

A polynomial with rational coefficients can sometimes be written as a product of lower-degree polynomials that also have rational coefficients.

In such cases, the polynomial is said to "factor over the rationals. Polynomials with rational coefficients always have as many roots, in the complex plane, as their degree; however, these roots are often not rational numbers. In such cases, the polynomial will not factor into linear polynomials.

Rational functions are quotients of polynomials. Like polynomials, rational functions play a very important role in mathematics and the sciences. Just as with rational numbers, rational functions are usually expressed in "lowest terms. Uh oh! Wolfram Alpha doesn't run without JavaScript. Please enable JavaScript.

Compute expert-level answers using Wolfram's breakthrough algorithms, knowledgebase and AI technology Example input More than just an online factoring calculator Wolfram Alpha is a great tool for factoring, expanding or simplifying polynomials.A root of a polynomial is a number such that. The fundamental theorem of algebra states that a polynomial of degree has roots, some of which may be degenerate.

For example, the roots of the polynomial. Finding roots of a polynomial is therefore equivalent to polynomial factorization into factors of degree 1.

Any polynomial can be numerically factored, although different algorithms have different strengths and weaknesses. Note that in the Wolfram Languagethe ordering of roots is different in each of the commands RootsNRootsand Table [ Root [ pk ], kn ]. In the Wolfram Languagealgebraic expressions involving Root objects can be combined into a new Root object using the command RootReduce. In this work, the th root of a polynomial in the ordering of the Wolfram Language 's Root object is denotedwhere is a dummy variable.

In this ordering, real roots come before complex ones and complex conjugate pairs of roots are adjacent. For example. Then Vieta's formulas give. Given an th degree polynomialthe roots can be found by finding the eigenvalues of the matrix. This method can be computationally expensive, but is fairly robust at finding close and multiple roots.

If the coefficients of the polynomial. This is known as the polynomial remainder theorem. If there are no negative roots of a polynomial as can be determined by Descartes' sign rulethen the greatest lower bound is 0.

Otherwise, write out the coefficientsletand compute the next line. Now, if any coefficients are 0, set them to minus the sign of the next higher coefficientstarting with the second highest order coefficient. If all the signs alternate, is the greatest lower bound. If not, then subtract 1 fromand compute another line. For example, consider the polynomial. If there are no positive roots of a polynomial as can be determined by Descartes' sign rulethe least upper bound is 0. Otherwise, write out the coefficients of the polynomialsincluding zeros as necessary. On the line below, write the highest order coefficient. Starting with the second-highest coefficientadd times the number just written to the original second coefficientand write it below the second coefficient. Continue through order zero.Wolfram Alpha can apply the quadratic formula to solve equations coercible into the form.

In doing so, Wolfram Alpha finds both the real and complex roots of these equations. It can also utilize other methods helpful to solving quadratic equations, such as completing the square, factoring and graphing. Enter your queries using plain English. To avoid ambiguous queries, make sure to use parentheses where necessary. Here are some examples illustrating how to ask about finding roots of quadratic equations.

Quadratic equations form parabolas when graphed, and have a wide variety of applications across many disciplines. In physics, for example, they are used to model the trajectory of masses falling with the acceleration due to gravity. Situations arise frequently in algebra when it is necessary to find the values at which a quadratic is zero.

In other words, it is necessary to find the zeros or roots of a quadratic, or the solutions to the quadratic equation. Relating to the example of physics, these zeros, or roots, are the points at which a thrown ball departs from and returns to ground level.

One common method of solving quadratic equations involves expanding the equation into the form and substituting theand coefficients into a formula known as the quadratic formula. This formula,determines the one or two solutions to any given quadratic. Sometimes, one or both solutions will be complex valued. Discovered in ancient times, the quadratic formula has accumulated various derivations, proofs and intuitions explaining it over the years since its conception. Some involve geometric approaches.

Others involve analysis of extrema. There are also many others. Those listed and more are often topics of study for students learning the process of solving quadratic equations and finding roots of equations in general.

Alternative methods for solving quadratic equations do exist. Completing the square, factoring and graphing are some of many, and they have use cases—but because the quadratic formula is a generally fast and dependable means of solving quadratic equations, it is frequently chosen over the other methods.
