That is the so-called fundamentaltheoremofalgebra.
这就是代数基本定理。

The latter is concluded by Gauss's famous "FundamentalTheoremofAlgebra".
后者以高斯的“代数方程的基本定理”作为结束。

This paper uses several methods of complex functions theorey to prove fundamentaltheoremofalgebra by argument principle, maximum modulus principle and minimum modulus principle.
