Which equation has the same solution as x^2+15+6=-2?

A. (x+7.5) ^2=48.25

B. (x-7.5) ^2=-64.25

C. (x-7.5) ^2=48.24

D. (x+7.5) ^2=64.25

the answer for this question is A. (x+7.5) ^2=48.25

Step-by-step explanation:

(x+7.5) ^2=48.25

x^2 + 7.5x + 7.5x + (7.5^2) = 48.25

x^2 + 15x + 56.25 = 48.25

x^2 + 15x + (56.25 - 48.25) = 0

x^2 + 15x + 8 = 0

and you forget to put 'x' at 15 on the question ...
