Solution for (x^2-2x)(y^2-4y)=4 equation: 


Simplifying
(x2 + -2x)(y2 + -4y) = 4

Reorder the terms:
(-2x + x2)(y2 + -4y) = 4

Reorder the terms:
(-2x + x2)(-4y + y2) = 4

Multiply (-2x + x2) * (-4y + y2)
(-2x * (-4y + y2) + x2(-4y + y2)) = 4
((-4y * -2x + y2 * -2x) + x2(-4y + y2)) = 4
((8xy + -2xy2) + x2(-4y + y2)) = 4
(8xy + -2xy2 + (-4y * x2 + y2 * x2)) = 4
(8xy + -2xy2 + (-4x2y + x2y2)) = 4
(8xy + -2xy2 + -4x2y + x2y2) = 4

Solving
8xy + -2xy2 + -4x2y + x2y2 = 4
