Lesson 7-7 Multiplying Polynomials

FOIL There are two methods that can be used to multiply polynomials
The first is called FOIL. FOIL Stands for: First Outer Inner Last

Example Use FOIL to solve Multiply the First Terms
Multiply the Outer Terms Multiply the Inner Terms Multiply the Last Terms Add the four products and combine Like Terms

Use FOIL to solve

Problems to Try Simplify by using the FOIL method. 1. 2.

The Distributive Property
The FOIL Method only works when you multiply two binomials The other method used in multiplying polynomials uses the Distributive Property The Distributive Property always works!

Example Use the Distributive Property to Solve
Split the first polynomial up and write each term multiplied by the second polynomial Distribute Multiply Combine Like Terms

Use the Distributive Property to Solve
FOIL would not work here!

Multiplying two trinomials
