Question

Factor completely: 2x2 − 4x − 48

Answer 1

@whpalmer4?

Answer 2

\[2x^2-4x-48\]

So what do you think we should do first? Do you see any common factors in all of those terms?

Answer 3

divide all of the terms by 2

Answer 4

Okay, that's a good start.

\[2(x^2-2x-24)\]Right?

Answer 5

yesh

Answer 6

is it 2(x − 6)(x + 4)?

Answer 7

yesh? have you been imbibing? :-)

Answer 8

no I just couldint figure the first part out! Thanks!

Answer 9

well, let's see!

\[(x-6)(x+4) = x(x+4) - 6(x+4) = x^2 + 4x -6x -24 = x^2 -2x -24\]
so if we multiply that by 2, we get our starting equation, good job!
