The fundamental theorem of algebra is the assertion that every polynomial with real or complex coefficients has at least one complex root. An immediate extension of this result is that every polynomial of degree $n$ with real or complex coefficients has exactly $n$ complex roots, when counting individually any repeated roots.

The fundamental theorem of algebra is a result from the field of analysis: Theorem 1.24 d’Alembert-Gauss’ fundamental theorem of algebra. The field ℂ of complex numbers is algebraically closed. Proof. Let g ∈ ℂ X be a polynomial of degree ≥ 1, and suppose that this polynomial does not have a root in ℂ. Fundamental theorem of algebra definition is - a theorem in algebra: every equation which can be put in the form with zero on one side of the equal-sign and a polynomial of degree greater than or equal to one with real or complex coefficients on the other has at least one root which is a real or complex number.

Every nonconstant polynomial with complex coefficients has a root in the complex numbers. Some version of the statement of the Fundamental Theorem of Algebra first appeared early in the 17th century in the writings of several mathematicians, including Peter Roth, Albert Girard, and Ren´e Descartes.

A clear notion of a polynomial equation, together with existing techniques for solving some of them, allowed coherent and ALGEBRA KEITH CONRAD Our goal is to use abstract linear algebra to prove the following result, which is called the fundamental theorem of algebra. Theorem 1. Any nonconstant polynomial with complex coe cients has a complex root. We will prove this theorem by reformulating it in terms of eigenvectors of linear operators. Let f(z) = zn + a n 1zn [13]S.Worfenstaim(1967), Proof of the Fundamental Theorem of algebra, Amer. Math.

The main argument in this note is similar to [2]. In [3] the reader can find The fundamental theorem of linear algebra concerns the following four subspaces associated with any matrix with rank (i.e., has independent columns and rows).
