The answer is A. Greatest common factor is 8xy because of the gcf and wat the equation has in common, xy. Then you are here- 8xy(?-?). Now, you have to find what's in the parenthesis. So, what number multiplied by 8xy gives you 32, you already have your variables, is 4. 8xy(4-?). Then what number multiplied by 8xy gives you -56z? It's -7z. So u r done. 8xy(4-7z).

I would like to help u if u would post another question with attached pic
(2x-15) + 11x = 180
Combine your like terms in get
13x - 15 = 180
Add 15 on both sides
13x - 15 = 180
+15 + 15
13x = 195
Divide each side by 13 and get
x = 15
