Exercise 24 Page 421

Find the product of the common prime factors.

5(x+1)

Practice makes perfect

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

5x+5

Rewrite

Rewrite 5x as 3 * x

5 * x+5

Rewrite

Rewrite 5 as 5 * 1

5 * x+5 * 1

FactorOut

Factor out 5

5(x+1)
