x^{2}+6x-y^{2}+10y-16
Consider x^{2}-y^{2}+6x+10y-16 as a polynomial over variable x.
\left(x+y-2\right)\left(x-y+8\right)
Find one factor of the form x^{k}+m, where x^{k} divides the monomial with the highest power x^{2} and m divides the constant factor -y^{2}+10y-16. One such factor is x+y-2. Factor the polynomial by dividing it by this factor.
