Answer:
B
Step-by-step explanation:
So for some reason the person didn't put the equations... I had the same question so here they are.
A.x^2 – 8x = 24
x2 – 8x + 4 = 24 + 4
B.x^2 – 8x = 24
x2 – 8x + 16 = 24 + 16
C.x^2 – 8x = 24
x2 – 8x + 64 = 24 + 64
D.x^2 – 8x = 24
x2 – 8x + 144 = 24 + 144
Good luck!
