Exercise 10 Page 111

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

14(3a+b)

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. 42a&= 2* 7 * 3 * a 14b&= 2* 7 * b In this case, the GCF is 2* 7 = 14. We are going to rewrite each term as 14 multiplied by some factor. Then we will use the Distributive Property to factor the expression. Let's go!
42a+14b
