4y^{2}-4xy-3x^{2}+4x-1
Consider 4y^{2}-4xy-3x^{2}+4x-1 as a polynomial over variable y.
\left(x+2y-1\right)\left(-3x+2y+1\right)
Find one factor of the form ky^{m}+n, where ky^{m} divides the monomial with the highest power 4y^{2} and n divides the constant factor -3x^{2}+4x-1. One such factor is x+2y-1. Factor the polynomial by dividing it by this factor.
