Simplifying
(3 + -1w)(5w + -9) = 0

Reorder the terms:
(3 + -1w)(-9 + 5w) = 0

Multiply (3 + -1w) * (-9 + 5w)
(3(-9 + 5w) + -1w * (-9 + 5w)) = 0
((-9 * 3 + 5w * 3) + -1w * (-9 + 5w)) = 0
((-27 + 15w) + -1w * (-9 + 5w)) = 0
(-27 + 15w + (-9 * -1w + 5w * -1w)) = 0
(-27 + 15w + (9w + -5w2)) = 0

Combine like terms: 15w + 9w = 24w
(-27 + 24w + -5w2) = 0
