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