Question

Factor the linear expression: 15x + 6












A) 2/5

B) -2/5

C) 3(5x + 2)

D) 5(3x + 6)

Answer 1

what's the GCF of 15x and 6?

Answer 2

Find the Greatest Comon Factor (GCF):
1. What is the largest number that divides evenly into 15x and 6? 3
2. What is the highest degree of x that divides evenly into 15x and 6? None, x is not in every term
3. Multiplying the results above, the GCF is 3
GCF=3

Factor out the GCF:
1. Put the GCF as the first term
2. Then, in parentheses, divide each term by the GCF
3(15x3+63)

Simplify each term in parenthises:
3(5x+2)

Answer 3

okay, that helped a lot, thank you :3
