m^{2}\left(x-y^{2}\right)+n\left(x-y^{2}\right)
Do the grouping m^{2}x-ny^{2}-m^{2}y^{2}+nx=\left(m^{2}x-m^{2}y^{2}\right)+\left(nx-ny^{2}\right), and factor out m^{2} in the first and n in the second group.
\left(x-y^{2}\right)\left(m^{2}+n\right)
Factor out common term x-y^{2} by using distributive property.
