Which expression is equivalent to 64 − 9x2?

a)(32)2 − (3x)2
b)(32)2 + (−3x)2
c)(8)2 − (3x)2
d)(8)2 + (−3x)2

XD okay so 8^2 is 64 - (3x)^2 and (3x)^2 is 3x3 which is 9 and x^2 so your answer will in turn be (8)^2-(3x)^2 the only reason i believe the last person said it was wrong is because they thought that if you squared the 3 would be postive but it cant be because its the sum of 3x squared not the sum of negative 3x squared. I just re read over what i wrote and even i dont understand but you get the point

Your answer is C
