You left out a sign.
Presuming you meant
\ =\ x^3\ -\ 6x^2\ +\ 9x)
Factor out 
\ =\ x\left(x^2\ -\ 6x\ +\ 9\right))
Now all that you need to do is factor the perfect square quadratic trinomial so that you have three factors. Set each factor equal to zero and solve each equation for
Or if you meant
\ =\ x^3\ +\ 6x^2\ +\ 9x)
then
\ =\ x\left(x^2\ +\ 6x\ +\ 9\right))
You still have a perfect square trinomial to factor.
