2\left(x+27x^{4}\right)
Factor out 2.
x\left(1+27x^{3}\right)
Consider x+27x^{4}. Factor out x.
\left(3x+1\right)\left(9x^{2}-3x+1\right)
Consider 1+27x^{3}. Rewrite 1+27x^{3} as \left(3x\right)^{3}+1^{3}. The sum of cubes can be factored using the rule: a^{3}+b^{3}=\left(a+b\right)\left(a^{2}-ab+b^{2}\right).
2x\left(3x+1\right)\left(9x^{2}-3x+1\right)
Rewrite the complete factored expression. Polynomial 9x^{2}-3x+1 is not factored since it does not have any rational roots.
