Wait can you check if this is right: 8(x^2 + 2x - 8) if that’s correct, this is the explanation: first look at all of your terms: 8x^2, 16x, and 64. find the greatest common factor which is 8 (because all of them have a factor of 8) factor the 8 out of all of the terms and put an 8 outside of the parenthesis. you will end up with 8(x^2 + 2x - 8)
