    yes ??

    what do you want to know ?

    for what values of x , f(x) equals zero ?

    x = 0, x = -3, x = 1

    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
