(x-y)(x-2y)=27

Solution for (x-y)(x-2y)=27 equation:

Simplifying
(x + -1y)(x + -2y) = 27

Multiply (x + -1y) * (x + -2y)
(x(x + -2y) + -1y * (x + -2y)) = 27
((x * x + -2y * x) + -1y * (x + -2y)) = 27

Reorder the terms:
((-2xy + x2) + -1y * (x + -2y)) = 27
((-2xy + x2) + -1y * (x + -2y)) = 27
(-2xy + x2 + (x * -1y + -2y * -1y)) = 27
(-2xy + x2 + (-1xy + 2y2)) = 27

Reorder the terms:
(-2xy + -1xy + x2 + 2y2) = 27

Combine like terms: -2xy + -1xy = -3xy
(-3xy + x2 + 2y2) = 27

Solving
-3xy + x2 + 2y2 = 27

Solving for variable 'x'.

Reorder the terms:
-27 + -3xy + x2 + 2y2 = 27 + -27

Combine like terms: 27 + -27 = 0
-27 + -3xy + x2 + 2y2 = 0

The solution to this equation could not be determined.
