Question

Factor out the GCF:

4x2 - 8x - 16

A. 4x(x2 - 2x - 4)
B. 4x(x - 2 - 4)
C. 4(x2 -2x - 4)
D. 4x(x - 2) - 16

Answer 1

4x^2 - 8x - 16....GCF is 4
4(x^2 - 2x - 4)

Answer 2

Step 1: The GCF in this situation is 4, so now you can reverse-distribute and you will get 4(x^2-2x-4)

Hope that helps!!!!!!
