3x^{2}\left(5x-4\right)+5x-4
Do the grouping 15x^{3}-12x^{2}+5x-4=\left(15x^{3}-12x^{2}\right)+\left(5x-4\right), and factor out 3x^{2} in 15x^{3}-12x^{2}.
\left(5x-4\right)\left(3x^{2}+1\right)
Factor out common term 5x-4 by using distributive property. Polynomial 3x^{2}+1 is not factored since it does not have any rational roots.
