Exercise 6 Page 418

Find the product of the common prime factors.

2 (7x -8y)

Practice makes perfect

To use the Distributive Property in reverse, we have to find the greatest common factor (GCF) between the terms. 14x&= 2 * 7 * x 16y&= 2 * 2 * 2 * 2 * y In this case, the GCF is the only prime factor, 2. Let's factor out the GCF for our expression.

14x-16y

Rewrite 14x as 2 * 7x

2 * 7x-16y

Rewrite 16y as 2 *8y

2 * 7x-2 *8y

Factor out 2

2 (7x -8y)
