Exercise 15 Page 113

Rewrite each term as a product of its prime factors to find the greatest common factor (GCF) between the terms.

3(y-8)

Practice makes perfect
To factor the expression, we have to find the greatest common factor (GCF) between the terms. Let's then rewrite each term as a product of its prime factors. 3y&= 3 * y 24&= 2 * 2* 2 * 3 In this case, the GCF is 3. We are going to rewrite each term as 3 multiplied by some factor. Then we will use the Distributive Property to factor the expression. Let's go!
