Answer:
-8, -7
Step-by-step explanation:
f(x)=x^2+15x+56
0 =x^2+15x+56
What two numbers multiply together to make 56 and add together to 15
7*8 = 56
7+8=15
0 = (x+8) (x+7)
Then use the zero product property
x+8 =0 x+7 =0
x+8-8 =0-8 x+7-7 =0-7
x=-8 x=-7
But it's not one doesn't always have to be the gcf
