How to think of a proof of the fundamental theorem of algebra Prerequisites A familiarity with polynomials and with basic real analysis. Statement Every polynomial (with arbitrary complex coefficients) has a root in the complex plane. (Hence, by the factor theorem, the number of roots of a polynomial, up to multiplicity, equals its degree.) Preamble How to come up with a proof. If you have heard of the impossibility of solving the quintic by radicals, or if you have simply tried and failed to solve such equations, then you will understand that it is unlikely that algebra alone will help us to find a solution of an arbitrary polynomial equation. In fact, what does it mean to solve a polynomial equation? When we `solve' quadratics, what we actually do is reduce the problem to solving quadratics of the particularly simple form x =C. In other words, our achievement is relative: if it is possible to find square roots, then it is possible to solve arbitrary quadratic equations. But is it possible to find square roots? Algebra cannot help us here. (What it can do is tell us that the existence of square roots does not lead to a contradiction of the field axioms. We simply "adjoin" square roots to the rational numbers and go ahead and do calculations with them - just as we adjoin i to the reals without worrying about its existence. See my

All Math Words Encyclopedia Home Fundamental Theorem of Algebra Pronunciation: /ˌfʌn dəˈmɛn tl ˈθi ər əm ʌv ˈæl dʒə brə/ The fundamental theorem of algebra states that every non-constant single variable polynomial with complex coefficients has at least one complex root. More importantly, for the level of math covered by this encyclopedia, the fundamental theorem of algebra implies that: Every non-constant polynomial with real coefficients can be factored over the real numbers into a product of linear factors and irreducible quadratic factors. A linear factor is a factor in the form bx+c where b and c are real numbers. A quadratic factor is a factor in the form ax +bx+c where a b and c are real numbers. A quadratic factor is irreducible if it can not be factored into two linear factors. The discriminant of a quadratic factor tells if the quadratic factor is reducible. If the discriminant is less than zero, the quadratic factor is irreducible. If the discriminant is greater or equal to zero, the quadratic factor can be reduce to two linear factors. The fundamental theorem of algebra is an existence theorem . While the fundamental theorem of algebra proves that the factors exist, it does not tell how to find the factors.

The Fundamental Theorem of Algebra The multiplicity of roots. Let's factor the polynomial . We can "pull out" a term Can we do anything else? No, we're done, we have factored the polynomial completely; indeed we have found the four linear (=degree 1) polynomials, which make up f x It just happens that the linear factor x shows up three times. What are the roots of f x )? There are two distinct roots: x =0 and x =-1. It is convenient to say in this situation that the root x =0 has multiplicity 3 , since the term x x -0) shows up three times in the factorization of f x ). Of course, the other root x =-1 is said to have multiplicity 1. We will from now on always count roots according to their multiplicity. So we will say that the polynomial has FOUR roots. Here is another example: How many roots does the polynomial have? The root x =1 has multiplicity 2, the root has multiplicity 3, and the root x =-2 has multiplicity 4. All in all, the polynomial has 9 real roots! Irreducible quadratic polynomials. A degree 2 polynomial is called a quadratic polynomial. In factoring quadratic polynomials, we naturally encounter three different cases:

55. Complex Numbers: The Fundamental Theorem Of Algebra Dave's Short Course on The Fundamental Theorem of Algebra As remarked before, in the 16th century Cardano noted that the sum of the three solutions to a cubic equation http://www.clarku.edu/~djoyce/complex/fta.html

Dave's Short Course on The Fundamental Theorem of Algebra As remarked before, in the 16th century Cardano noted that the sum of the three solutions to a cubic equation x bx cx d b , the negation of the coefficient of x . By the 17th century the theory of equations had developed so far as to allow Girard (1595-1632) to state a principle of algebra, what we call now "the fundamental theorem of algebra". His formulation, which he didn't prove, also gives a general relation between the n solutions to an n th degree equation and its n coefficients. An n th degree equation can be written in modern notation as x n a x n a n x a n x a n where the coefficients a a n a n , and a n are all constants. Girard said that an n th degree equation admits of n solutions, if you allow all roots and count roots with multiplicity. So, for example, the equation x x x + 1 = has the two solutions 1 and 1. Girard wasn't particularly clear what form his solutions were to have, just that there be n of them: x x x n , and x n Girard gave the relation between the n roots x x x n , and x n and the n coefficients a a n a n , and a n that extends Cardano's remark. First, the sum of the roots

The fundamental theorem of algebra Algebra index History Topics Index Version for printing The Fundamental Theorem of Algebra (FTA) states Every polynomial equation of degree n with complex coefficients has n roots in the complex numbers. In fact there are many equivalent formulations: for example that every real polynomial can be expressed as the product of real linear and real quadratic factors. Early studies of equations by al-Khwarizmi (c 800) only allowed positive real roots and the FTA was not relevant. Cardan was the first to realise that one could work with quantities more general than the real numbers. This discovery was made in the course of studying a formula which gave the roots of a cubic equation. The formula when applied to the equation x x Cardan knew that the equation had x = 4 as a solution. He was able to manipulate with his 'complex numbers' to obtain the right answer yet he in no way understood his own mathematics. Bombelli , in his Algebra , published in 1572, was to produce a proper set of rules for manipulating these 'complex numbers'. Descartes in 1637 says that one can 'imagine' for every equation of degree n n roots but these imagined roots do not correspond to any real quantity.

Fundamental Theorem of Algebra The fundamental theorem of algebra (FTA) states Every polynomial of degree n with complex coefficients has n roots in the complex numbers. There are many other equivalent versions of this, for example that every real polynomial can be expressed as the product of real linear and real quadratic factors. Early work with equations only considered positive real roots so the FTA was not relevant. Cardan realized that one could work with numbers outside of the reals while studying a formula for the roots of a cubic equation. While solving x = 15x + 4 using the formula he got an answer involving the square root of -121. He manipulated this to obtain the correct answer, x = 4, even though he did not understand exactly what he was doing with these "complex numbers." In 1572 Bombelli created rules for these "complex numbers." In 1637 Descartes said that one can "imagine" for every equation of degree n n roots, but these imagined roots do not correspond to any real quantity. Albert Girard , a Flemish mathematiciam, was the first to claim that there are always n solutions to a polynomial of degree n in 1629 in . He does not say that the solutions are of the form a + b i , a, b real. Many mathematicians accepted Girard's claim that a polynomial equation must have
