Factor Completely
2x^3-40x^2-192x
I have a common factor of x so I rewrote the problem as
x(x^2-40x+192) then trying to use FOIL rewrote as
(x ) (x )
And that is where i'm stuck.

You factored out the 2x incorrectly. You should end up with 2x(x^2-20x+96).
The expression in parentheses can be factored into
(x-12)(x-8).
Now put it all together.
