Hello, I'm having trouble factoring:

-3x^2 - 4x + 4

I'm trying to find two different x's because towards the end I'm supposed to have two solutions x = "something" / x = "something2".

I'm stuck where I find two #'s that can make the middle term = -4.

(x - 2)(x - 6)

Assistance will be appreciated,

Thank you!
