Which equation is equivalent to the given equation?

x^2+16x=22

a. (x+8)^2=86 b. (x+8)^2=38 c. (x+16)^2= 278 d. (x+4)^2= 22

Expand (x+8)^{2} in answer A. and obtain x^{2} + 16x + 64 = 86

When you subtract 64 from both sides, it is x^{2} + 16x = 22

So the correct answer is selection a. as in applesauce.
