Simplifying
(2 + y)(2y + -9) = 0

Reorder the terms:
(2 + y)(-9 + 2y) = 0

Multiply (2 + y) * (-9 + 2y)
(2(-9 + 2y) + y(-9 + 2y)) = 0
((-9 * 2 + 2y * 2) + y(-9 + 2y)) = 0
((-18 + 4y) + y(-9 + 2y)) = 0
(-18 + 4y + (-9 * y + 2y * y)) = 0
(-18 + 4y + (-9y + 2y2)) = 0

Combine like terms: 4y + -9y = -5y
(-18 + -5y + 2y2) = 0
