Solution for (x-3y)(x-3y)= equation:


Simplifying
(x + -3y)(x + -3y) = 0

Multiply (x + -3y) * (x + -3y)
(x(x + -3y) + -3y * (x + -3y)) = 0
((x * x + -3y * x) + -3y * (x + -3y)) = 0

Reorder the terms:
((-3xy + x2) + -3y * (x + -3y)) = 0
((-3xy + x2) + -3y * (x + -3y)) = 0
(-3xy + x2 + (x * -3y + -3y * -3y)) = 0
(-3xy + x2 + (-3xy + 9y2)) = 0

Reorder the terms:
(-3xy + -3xy + x2 + 9y2) = 0

Combine like terms: -3xy + -3xy = -6xy
(-6xy + x2 + 9y2) = 0

Solving
-6xy + x2 + 9y2 = 0

Solving for variable 'x'.
