Multiplying Polynomials

Overview

Goal. Multiply polynomials of any length: distribute a monomial over every term, use FOIL for two binomials, and multiply term by term for longer polynomials, then combine like terms.

Distributive property (definition). Multiplying a sum by a number means multiplying each term of the sum by that number: a(b + c) = ab + ac.

Distributing, FOIL, and term-by-term multiplication.

Interactive Activity

Goal. Multiply polynomials by sending every term of the first polynomial times every term of the second — a monomial times each term, FOIL for two binomials, and one term at a time for longer polynomials.

FOIL (definition). A way to organize multiplying two binomials: First terms, Outside terms, Inside terms, Last terms.
