Question

Factor completely: −4x^2 + 16x − 24

−1(x^2 − 16x + 24)

−4(x^2 − 4x + 6)

−4x(x^2 − 4x + 6)

−4(x^2 + 4x − 6)

Answer 1

what is the GCF os -4, +16, -24

Answer 2

idk how to do that

Answer 3

GCF is greatest common factor...so what is the greatest number that you can divide out of all of those.

Answer 4

is it 1 ?

Answer 5

no, keep going up. that would be the LOWEST not greatest.

Answer 6

idk how to do GCF with negative numbers

Answer 7

well then do it as if they were all positive and then we will go over the negative part.

Answer 8

what number goes into 4, 16 and 24 evenly ?

Answer 9
