Simplifying
(9 + w)(4w + -3) = 0

Reorder the terms:
(9 + w)(-3 + 4w) = 0

Multiply (9 + w) * (-3 + 4w)
(9(-3 + 4w) + w(-3 + 4w)) = 0
((-3 * 9 + 4w * 9) + w(-3 + 4w)) = 0
((-27 + 36w) + w(-3 + 4w)) = 0
(-27 + 36w + (-3 * w + 4w * w)) = 0
(-27 + 36w + (-3w + 4w2)) = 0

Combine like terms: 36w + -3w = 33w
(-27 + 33w + 4w2) = 0
