x^{2}+\left(-8-3y\right)x+16+12y
Consider x^{2}-8x+16-3xy+12y as a polynomial over variable x.
\left(x-4\right)\left(x-3y-4\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 12y+16. One such factor is x-4. Factor the polynomial by dividing it by this factor.
