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