Lesson 92 • Areas of Rectangles with Variable Dimensions • Products of Binomials

### Slide 5:

Multiply polynomials horizontally using FOIL (2 x + 3)(4 x + 1) First Outer Inner Last = 8 x 2 + 2 x + 12 x + 3 FOIL PATTERN The letters of the word FOIL can help you to remember how to use the distributive property to multiply binomials. The letters should remind you of the words First, Outer, Inner, and Last. F O I L 8 x 2 + 14 x + 3

### Slide 6:

Multiply binomials using the FOIL pattern EXAMPLE 5 Find the product (3 a + 4)( a – 2). ( 3 a + 4 )( a – 2 ) 3 a 2 First Outside Inside – 6 a Last + 4 a – 8 3 a 2 – 2 a – 8

### Slide 7:

GUIDED PRACTICE for Examples 3, 4, and 5 Find the product. 1. (4 b –5)( b – 2) ANSWER 4 b 2 – 13 b + 10
