Solving Polynomial Equations in Factored Form

Overview

Goal. Solve polynomial equations written in factored form by using the Zero Product Property: set each factor equal to zero and solve the resulting small equations.

Zero Product Property (definition). If the product of two or more factors is zero, then at least one of the factors must be zero.
