If 8x = x 2 + 15, then which of the following can be used to find x?

(x + 3)(x + 5) = 0
x(8 - x) = 15
(x - 3)(x - 5) = 0

The step used (x-5)(x-3)=0

C is correct

Step-by-step explanation:

Given:

We need to factor it.

First we move all term same side and then we factor is.

Now we split middle term

Make group and factor each group

Hence, The step used (x-5)(x-3)=0
