Question

Help! I keep working it out, but I cannot get any of the answer choices!

Answer 1

Your answer is A. (2x - 4)^2

Answer 2

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

Answer 3

Thank you alot !!Is there a way to work it out step by step? (Besides just checking the answers?)

Answer 4

If I was factoring it I would factor out a 4
4(x^2 - 4x +4)

next I would factor x^2 -4x + 4
the +4 means both value are the same sign.
the -4x means they are negative

now I list the factors for the +4, and make them both negative:
-1,-4
-2,-2
and add them up
if we get -4, we found the factors. that means -2 and -2 are the factors, and we have
4(x-2)(x-2)
that looks different from your answers, but we can write it like this:
2*(x-2) * 2*(x-2)

and distribute the 2's to get
(2x-4) * (2x-4)
and finally

(2x-4)^2

Answer 5

That is exactly what I got, I just could not figure out how on Earth they went from a 4 to a 2 in the beginning! Thank you for the explanations yall! I understand the question now!
