Factor x^2 - 8x + 16

a. 4(x2 - 2x + 4)

b. (x - 4)(x + 4)

c. (x - 4)(x - 4)

d. (x + 4)(x + 4)

X^2-8x+16 = x^2-2*x*4+4^x => (x-4)^2 => C

Iwould say d but i am not 100% positive

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.
