Consider x^ {2}-64. Rewrite x^ {2}-64 as x^ {2}-8^ {2}. The difference of squares can be factored using the rule: a^ {2}-b^ {2}=\left (a-b\right)\left (a+b\right).

Substitute the values a = 1 a = 1, b = 0 b = 0, and c = −64 c = - 64 into the quadratic formula and solve for x x.

2019年1月11日 · The solution to the equation x2 = 64 is x = ±8, meaning the two solutions are 8 and -8. Among the provided options, the positive solution 8 is given as A. Therefore, the answer is A. 8.
