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.

    The last one shold be

    (x ) (x )

    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.
