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


Simplifying
(x + -1y)(4x + -2y) = 0

Multiply (x + -1y) * (4x + -2y)
(x(4x + -2y) + -1y * (4x + -2y)) = 0
((4x * x + -2y * x) + -1y * (4x + -2y)) = 0

Reorder the terms:
((-2xy + 4x2) + -1y * (4x + -2y)) = 0
((-2xy + 4x2) + -1y * (4x + -2y)) = 0
(-2xy + 4x2 + (4x * -1y + -2y * -1y)) = 0
(-2xy + 4x2 + (-4xy + 2y2)) = 0

Reorder the terms:
(-2xy + -4xy + 4x2 + 2y2) = 0

Combine like terms: -2xy + -4xy = -6xy
(-6xy + 4x2 + 2y2) = 0

Solving
-6xy + 4x2 + 2y2 = 0

Solving for variable 'x'.

Factor out the Greatest Common Factor (GCF), '2'.
