Multiply (x + 5y) * (9x + -1y)
(x(9x + -1y) + 5y * (9x + -1y)) = 0
((9x * x + -1y * x) + 5y * (9x + -1y)) = 0

Reorder the terms:
((-1xy + 9x2) + 5y * (9x + -1y)) = 0
((-1xy + 9x2) + 5y * (9x + -1y)) = 0
(-1xy + 9x2 + (9x * 5y + -1y * 5y)) = 0
(-1xy + 9x2 + (45xy + -5y2)) = 0

Reorder the terms:
(-1xy + 45xy + 9x2 + -5y2) = 0
