m^{2}-2nm-35n^{2}
Consider m^{2}-2mn-35n^{2} as a polynomial over variable m.
\left(m-7n\right)\left(m+5n\right)
Find one factor of the form m^{k}+p, where m^{k} divides the monomial with the highest power m^{2} and p divides the constant factor -35n^{2}. One such factor is m-7n. Factor the polynomial by dividing it by this factor.
