The FOIL Method

In this lesson, we will look into how to use the FOIL method to distribute two binomials

 

 

Most Algebra books describe FOIL as a method of multiplying two binomials.

FOIL is the acronym for

First

Outside

Inside

Last

 

 

Example:

Multiply the binomials (x + 1)(2x – 3)

Solution:

(x + 1)(2x – 3)

Multiply First : x • 2x = 2 x2
Multiply Outside : x • (–3) = –3x
Multiply Inside : 1 • 2x = 2x
Multiply Last : 1 • (–3) = –3

(x + 1)(2x – 3)
= 2x2 – 3x + 2x – 3
= 2x2x – 3
