What do you want done with it?

Are you multiplying it or finding all the values for x?

x=0, -3, 1

if you are multiplying it out:

(x^2 + 3x)(x -1) = x^3 + 2x^2 - 3x

if you want to know if it's factored, correctly, yes. if you want to multiply it out, it would be

x(x^2 - x + 3x -3) = x(x^2 + 2x -3) =

x^3 + 2x^2 - 3x

the values at which f(x) is 0: 0, 1, -3

x(x+3) is Xsquared +3X

then

(Xsquared -3X)(X-1)

so

Xcubed -3Xsquared -3X

just foil it all out
