Question

Find the GCF: 8x2, -4x, -20

Answer 1

First you want to break down each expression into its components.
For example
12 = 2 times 2 times 3
6x2 = 2 times 3 times x times x
(i'm writing out times so it won't be confused with "x")
So, can you break down 8x2, 4x and 20 into their components. Don't worry about the minus sign in front of your last 2 expressions.
