Ask yourself, what two numbers when added equal -5 and when multiplied equal 6(the leading coefficient of -6 must be accounted for, -6(-1)=6).

Let's see...-3 and -2.....(-3)(-2)=6 and -3+(-2)=-5

Factor:

First, factor out 2x:Q4:

-30x^3 + 2x^2 + 12x

?? -> One term with ^3 and another with ^2, how do you do this?

Now, the quadratic in the parentheses factors:

Same as before:

What 2 numbers when multiplied equal -90,(-15*6), and when added equal 1.

10 and -9?. Yep.
