Question

Factor completely: 2x2 − 16x + 32

2(x + 4)(x + 4)

(2x − 8)(x − 4)

(2x − 16)(x − 2)

2(x − 4)(x − 4)

Answer 1

@jigglypuff314 C?

Answer 2

Nope.
Take the factor 2 out of the expression.
Then try finding the factors.

Answer 3

always take out greatest common factor first, so factor out a 2 so that
2x^2 − 16x + 32 = 2(x^2 - 8x + 16)
^ ^ two numbers that multiply to 16 and add to -8

Answer 4

Dang I'm not sure!

Answer 5

it has been narrowed to two options because of the factored out 2
now, what two numbers add to -8
^

Answer 6

B?

Answer 7

it has been narrowed to two options because of the factored out 2
so the choices have to be one with a 2 alone in front so it can't be B or C

Answer 8

D!

Answer 9

yes :)

Answer 10
