I want to graph the equation : P(x)= x^3 + x^2 -12x I was thinking that I would combine
the x-values, but then I could not use the complete the square technique. Would I have to
just solve the second half of the equation and then graph x^3 separately

Hi Sean,

First take out the common factor of x to get

P(X) = x(x^{2} + x - 12)

Now factor x^{2} + x - 12.

If you need further assistance write back.
