@article{deOliveira2012TheFT, title={The Fundamental Theorem of Algebra: From the Four Basic Operations}, author={Oswaldo Rio Branco de Oliveira}, journal={The American Mathematical Monthly}, year={2012}, volume={119}, pages={753 - 758} }
Abstract This paper presents an elementary and direct proof of the Fundamental Theorem of Algebra, via Weierstrass’ Theorem on Minima, that avoids the following: all root extractions, angles, non-algebraic functions, differentiation, integration, series, and arguments by induction.

One of the simplest proofs that every nontrivial polynomial P has a zero goes as follows. Observe that |P(z)| → ∞ as |z| → ∞, so we may find an R > 0 with |P(z)| > |P(0)| for all |z| ≥ R. Since any…
