x^{2}-8x-33-14y-y^{2}
Consider x^{2}-8x-33-14y-y^{2} as a polynomial over variable x.
\left(x+y+3\right)\left(x-y-11\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}-14y-33. One such factor is x+y+3. Factor the polynomial by dividing it by this factor.
