    I would suggest to multiply each term with it's corresponding term.

    So start by multiplying \[2x^2\] with everything on the right parenthesis and then multiply \[6\] with everything on the right parenthesis

    \[2x(3x^2-3x-6) + -6(3x^2-3x-6)\] Can you do that?

    (2x - 6)(3x2 - 3x - 6) 6x^3 - 6x^2 - 12x - 18x^2 + 18x + 36 6x^3 - 24x^2 + 6x + 36 You do a concept similar to FOILing. Just go in the same order.
