    Answer:

    x^3+7x^2-50x-336 or (x-7)(x+6)(x+8)

    Step-by-step explanation:

    Factor each equation.

    x^2-x-42= (x-7)(x+6)

    x^2+x-56= (x-7)(x+8)

    The common factor is (x-7), therefore the other factors of the expressions must multiply to find the common factor.

    (x-7)(x+6)(x+8)=x^3+7x^2-50x-336.
