y\left(8y^{3}-1\right)
Factor out y.
\left(2y-1\right)\left(4y^{2}+2y+1\right)
Consider 8y^{3}-1. Rewrite 8y^{3}-1 as \left(2y\right)^{3}-1^{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).
y\left(2y-1\right)\left(4y^{2}+2y+1\right)
Rewrite the complete factored expression. Polynomial 4y^{2}+2y+1 is not factored since it does not have any rational roots.
