The many facets of factoring polynomials and solving polynomial equations are explained here in great detail. Taking students from basic definitions through the Descartes Rule of Signs, this is a valuable tool for math classes.

This comprehensive study guide highlights the main terms and formulas needed to review solving rational equations. Examples are included.

A comprehensive look at the three main ways to find the roots of a polynomial: factoring, formulas, and the rational root theorem.

To solve polynomials of higher degree, use synthetic division as demonstrated here. The Rational Zero Theorem, Upper and Lower Bound Theorem, and Descartes Rule of Signs are explained.

Explains the reasoning and methodology for the process of numerically approximating the zeroes of a non solvable polynomial.

College professor Dan Bach presents a review of algebra concepts, including factoring, quadratic equations, and graphing parabolas. The examples are detailed, but easy to follow. This is a good site for reviewing before tests and quizzes.
