Factor completely x2 − 8x + 16.

Question

(x + 4)(x + 4)
(x − 4)(x − 4)
(x + 4)(x − 4)
(x − 2)(x − 8)

i don't understand this

Answer 1

(x + 4)(x − 4)

Find the GCF and then factor it in the solution

Answer 2

so it would be the third one?

Answer 3

No. (x+4)(x-4) = x^2-16

(x-4)(x-4) = x^2-8x+16

Answer 4

so the second one?
