GOAL: MULTIPLY TWO POLYNOMIALS TOGETHER USING THE DISTRIBUTIVE PROPERTY ELIGIBLE CONTENT: A Multiplying Polynomials
Vocabulary Distributive Property – multiplying the term outside the parentheses by every term inside the parentheses. When you multiply variables together: You ADD the exponents!
Monomial times Polynomial
Examples
A.6x 2 + 9x + 15 B.6x 3 + 9x x C.5x 3 + 6x 2 + 8x D.6x 2 + 3x + 5 Find 3x(2x 2 + 3x + 5).
Binomial times Polynomial Distribute each term of the binomial.
Vocabulary Box Method – a method used to multiply polynomials.
The Box Method
Examples
A.12z 3 + 9z z B.8z 2 + 6z + 10 C.12z 3 + z 2 + 9z + 10 D.12z z z + 10 A. Find (3z + 2)(4z 2 + 3z + 5).
