(3x + 5y)(x + -6y) = 0

Multiply (3x + 5y) * (x + -6y)
(3x * (x + -6y) + 5y * (x + -6y)) = 0
((x * 3x + -6y * 3x) + 5y * (x + -6y)) = 0

Reorder the terms:
((-18xy + 3x2) + 5y * (x + -6y)) = 0
((-18xy + 3x2) + 5y * (x + -6y)) = 0
(-18xy + 3x2 + (x * 5y + -6y * 5y)) = 0
(-18xy + 3x2 + (5xy + -30y2)) = 0

Reorder the terms:
(-18xy + 5xy + 3x2 + -30y2) = 0
