Theorems about polynomials | Articles containing proofs | Theorems in complex analysis | Field (mathematics)
The fundamental theorem of algebra, also known as d'Alembert's theorem, or the d'Alembert–Gauss theorem, states that every non-constant single-variable polynomial with complex coefficients has at least one complex root. This includes polynomials with real coefficients, since every real number is a complex number with its imaginary part equal to zero. Equivalently (by definition), the theorem states that the field of complex numbers is algebraically closed. The theorem is also stated as follows: every non-zero, single-variable, degree n polynomial with complex coefficients has, counted with multiplicity, exactly n complex roots. The equivalence of the two statements can be proven through the use of successive polynomial division. Despite its name, there is no purely algebraic proof of the theorem, since any proof must use some form of the analytic completeness of the real numbers, which is . Additionally, it is not fundamental for modern algebra; its name was given at a time when algebra was synonymous with theory of equations. (Wikipedia).

Here we give restatements of the Fundamental theorems of Algebra (I) and (II) that we critiqued in our last video, so that they are now at least meaningful and correct statements, at least to the best of our knowledge. The key is to abstain from any prior assumptions about our understandin

The Fundamental Theorem of Algebra is a statement about the relationship between the number of solutions a polynomial has and the degree of that polynomial. Namely, a polynomial will have the same number of solutions as its degree (once we count something called multiplicities). Subscrib
