s^{2}\left(s-3\right)+3\left(s-3\right)
Do the grouping s^{3}-3s^{2}+3s-9=\left(s^{3}-3s^{2}\right)+\left(3s-9\right), and factor out s^{2} in the first and 3 in the second group.
\left(s-3\right)\left(s^{2}+3\right)
Factor out common term s-3 by using distributive property. Polynomial s^{2}+3 is not factored since it does not have any rational roots.
