Question

Picture shown please help !!!

Answer 1

Let's factor the top and the bottom.
Top factors 4x + 20 = 4(x + 5)
Bottom x^2 + 2x - 15 = (x + 5)(x - 3)

The gcf is the largest value that will go into both the top and the bottom.  In our problem the ONLY thing that will go into top and bottom is x + 5 so that is your GCF. (c)
