x\left(x^{3}-27\right)
Factor out x.
\left(x-3\right)\left(x^{2}+3x+9\right)
Consider x^{3}-27. Rewrite x^{3}-27 as x^{3}-3^{3}. The difference of cubes can be factored using the rule: a^{3}-b^{3}=\left(a-b\right)\left(a^{2}+ab+b^{2}\right).
x\left(x-3\right)\left(x^{2}+3x+9\right)
Rewrite the complete factored expression. Polynomial x^{2}+3x+9 is not factored since it does not have any rational roots.
