Exercise 27 Page 421

Find the product of the common prime factors.

5(2x-7)

Practice makes perfect

To use the Distributive Property in reverse, we have to find the greatest common factor (GCF) between the terms. 10x&=2 * 5 * x 35&= 5 * 7 In this case, the GCF is the only common prime factor, 5. Let's factor out the GCF for our expression.

10x- 35

Rewrite 10x as 5 * 2x

5 * 2x - 35

Rewrite 35 as 5 * 7

5 * 2x - 5* 7

Factor out 5

5(2x-7)
