x^{3}\left(x^{4}-81\right)
Factor out x^{3}.
\left(x^{2}-9\right)\left(x^{2}+9\right)
Consider x^{4}-81. Rewrite x^{4}-81 as \left(x^{2}\right)^{2}-9^{2}. The difference of squares can be factored using the rule: a^{2}-b^{2}=\left(a-b\right)\left(a+b\right).
\left(x-3\right)\left(x+3\right)
Consider x^{2}-9. Rewrite x^{2}-9 as x^{2}-3^{2}. The difference of squares can be factored using the rule: a^{2}-b^{2}=\left(a-b\right)\left(a+b\right).
x^{3}\left(x-3\right)\left(x+3\right)\left(x^{2}+9\right)
Rewrite the complete factored expression. Polynomial x^{2}+9 is not factored since it does not have any rational roots.
