What are the factors of x2 − 64?
prime
(x − 4)(x + 16)
(x − 8)(x − 8)
(x + 8)(x − 8)

Well, should be likee thiss correct meh if im wrong or what ever, but
 the answer would be, last one (x + 8)(x - 8), well 1, is because the 64 is a negative so if you would just take that 64 and bring it down then look at this onece the work is donee then when u add the 2 numbers that x would be x² or x2 n  that - 64 is that + 8 (-8) witch would equal out so if you really look at it the CORRECT ANSWER WOULD BE B. (x - 8)(x -8)

 i realli understand if youu don't then comment in the sec beloww↓
