      The Fundamental Theorem of Algebra is not limited to what can be seen graphically; it applies to real and complex roots. Real and complex roots of higher degree polynomials can be found using the Factor Theorem, Remainder Theorem, Rational Root Theorem, and Fundamental Theorem of Algebra, incorporating complex and radical conjugates.
