Given expression is:
4 y + 3 x - 3 x y - 4 y^2
Regroup terms after interchanging their positions.
4 y - 4 y^2 + 3 x - 3 x y
Regrouping now, we get
4 y (1 - y) + 3 x (1 - y)
(4 y + 3 x) * (1 - y)
These are the two factors.
4 y + 3 x - 3 x y - 4 y^2
Regroup terms after interchanging their positions.
4 y - 4 y^2 + 3 x - 3 x y
Regrouping now, we get
4 y (1 - y) + 3 x (1 - y)
(4 y + 3 x) * (1 - y)
These are the two factors.
