5x^{2}+\left(y+1\right)x-4y^{2}+y
Consider 5x^{2}+xy-4y^{2}+x+y as a polynomial over variable x.
\left(x+y\right)\left(5x-4y+1\right)
Find one factor of the form kx^{m}+n, where kx^{m} divides the monomial with the highest power 5x^{2} and n divides the constant factor -4y^{2}+y. One such factor is x+y. Factor the polynomial by dividing it by this factor.
