How do I solve:
-9x + 2x to the third power +8x -12x to the third power

    Isn't there suppsed to be an "=" sign in there somewhere? If so, where?

    You can't "solve" it if it isn't an equation.

    (-7x)^3=(-7)^3 *x^3=-343x^3


    (-4x)^3=(-4)^3 *x^3=-64x^3

    -343x^3 +(-64x^3)=
    -343x^3-64x^3= -407x^3
