Module 2  Topic 1  Relating Factors and Zeros
"Now that students are familiar with the key characteristics of polynomial functions, Relating Factors and Zeros presents them with opportunities to analyze, factor, solve, and sketch polynomial functions given algebraic representations ... They then turn their attention to polynomials that cannot be factored and learn to divide polynomials when one factor is known, using long division and synthetic division to write a polynomial in factored form."
