4. Factor using the GCF 12a - 30

Answer 1

To factor using the Greatest Common Factor (GCF) of 12a - 30, we first need to find the GCF of the two terms. In this case, the GCF is 6.

Next, we divide each term by the GCF:

12a ÷ 6 = 2a
30 ÷ 6 = 5

So the expression 12a - 30 can be factored as:

6(2a - 5)
