-6m^{2}+\left(3+7n\right)m-3n-n^{2}
Consider 3m-3n-6m^{2}+7mn-n^{2} as a polynomial over variable m.
\left(-m+n\right)\left(6m-n-3\right)
Find one factor of the form km^{p}+q, where km^{p} divides the monomial with the highest power -6m^{2} and q divides the constant factor -n^{2}-3n. One such factor is -m+n. Factor the polynomial by dividing it by this factor.
