Question 114952: Factor 3x^3 - 6x^2 - 24x

Factor 3x%5E3 - 6x%5E2 - 24x
What we need to do here is gather the common factors. These terms have a common factor of 3 and a common factor of x, so we can factor out a 3x:
3x(x%5E2 - 2x - 8)
Now we need to see if x%5E2-2x-8 can be factored further. Can we find factors of -8 that sum to -2? Yes, -4 and 2.
Which makes the answer --
3x(x-4)(x+2)
