Multiply and combine like terms.
\left(x-3\right)\left(x^{2}+3x+9\right)
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). Polynomial x^{2}+3x+9 is not factored since it does not have any rational roots.
x^{3}-27
Calculate 3 to the power of 3 and get 27.
