Exercise 14 Page 113

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

2(4x+1)

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. 8x&= 2* 2 * 2 * x 2&= 2 In this case, the GCF is 2. We are going to rewrite each term as 2 multiplied by some factor. Then we will use the Distributive Property to factor the expression. Let's go!
