Simplifying
(3x + -2y)(3x + 2y) = 0

Multiply (3x + -2y) * (3x + 2y)
(3x * (3x + 2y) + -2y * (3x + 2y)) = 0
((3x * 3x + 2y * 3x) + -2y * (3x + 2y)) = 0

Reorder the terms:
((6xy + 9x2) + -2y * (3x + 2y)) = 0
((6xy + 9x2) + -2y * (3x + 2y)) = 0
(6xy + 9x2 + (3x * -2y + 2y * -2y)) = 0
(6xy + 9x2 + (-6xy + -4y2)) = 0

Reorder the terms:
(6xy + -6xy + 9x2 + -4y2) = 0

Combine like terms: 6xy + -6xy = 0
(0 + 9x2 + -4y2) = 0
(9x2 + -4y2) = 0

Solving
9x2 + -4y2 = 0

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '4y2' to each side of the equation.
