What Does the Fundamental Theorem of Algebra Tell Us about a Function?

By AutenA2Math

This video explains the Fundamental Theorem of Algebra and how it can assist us when solving a polynomial equation. (For those not familiar with the technique, this video demonstrates the use of "synthetic division.") Remember that the Fundamental Theorem of Algebra only applies when working in the Complex Number set. A polynomial like x^2 + 1 has no real roots, but it does have two complex roots.
