3\left(6x^{3}-2x^{2}+15x-5\right)
Factor out 3.
2x^{2}\left(3x-1\right)+5\left(3x-1\right)
Consider 6x^{3}-2x^{2}+15x-5. Do the grouping 6x^{3}-2x^{2}+15x-5=\left(6x^{3}-2x^{2}\right)+\left(15x-5\right), and factor out 2x^{2} in the first and 5 in the second group.
\left(3x-1\right)\left(2x^{2}+5\right)
Factor out common term 3x-1 by using distributive property.
3\left(3x-1\right)\left(2x^{2}+5\right)
Rewrite the complete factored expression. Polynomial 2x^{2}+5 is not factored since it does not have any rational roots.
