Simplifying
(3x + -1y)(3x + -1y) = 0

Multiply (3x + -1y) * (3x + -1y)
(3x * (3x + -1y) + -1y * (3x + -1y)) = 0
((3x * 3x + -1y * 3x) + -1y * (3x + -1y)) = 0

Reorder the terms:
((-3xy + 9x2) + -1y * (3x + -1y)) = 0
((-3xy + 9x2) + -1y * (3x + -1y)) = 0
(-3xy + 9x2 + (3x * -1y + -1y * -1y)) = 0
(-3xy + 9x2 + (-3xy + 1y2)) = 0

Reorder the terms:
(-3xy + -3xy + 9x2 + 1y2) = 0

Combine like terms: -3xy + -3xy = -6xy
(-6xy + 9x2 + 1y2) = 0

Solving
-6xy + 9x2 + 1y2 = 0
