1. Lesson 7-7 Multiplying Polynomials

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

3. 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

4. Use FOIL to solve

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

6. 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!

7. 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

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

9. Multiplying two trinomials

10. Problems to Try
Simplify using the Distributive Property 1. 2. 3.

11. Word Problem
Translate the equation
Substitute your values
Simplify

12. Problem to Try 1.
