Unit 4 Lesson 4: Solving Polynomial Equations State StandardsLesson Goals 3: Add, subtract, multiply and divide (including long division) polynomials. 4: Factor polynomials representing the difference of squares, perfect square trinomials, and the sum and difference of two cubes. Factor polynomial expressions Use factoring to solve polynomial equations ESLRs: Becoming Competent Learners and Complex Thinkers

2
Previously in Math Factoring Quadratic Equations ▫Use the Distributive Property (look for a GCF) ▫Check for special case Perfect Square Trinomial Difference of Two Squares ▫“Unfoil” aka “The I-thing”
