Simplifying
4w(w + 2)(w + 9) = 0

Reorder the terms:
4w(2 + w)(w + 9) = 0

Reorder the terms:
4w(2 + w)(9 + w) = 0

Multiply (2 + w) * (9 + w)
4w(2(9 + w) + w(9 + w)) = 0
4w((9 * 2 + w * 2) + w(9 + w)) = 0
4w((18 + 2w) + w(9 + w)) = 0
4w(18 + 2w + (9 * w + w * w)) = 0
4w(18 + 2w + (9w + w2)) = 0

Combine like terms: 2w + 9w = 11w
4w(18 + 11w + w2) = 0
(18 * 4w + 11w * 4w + w2 * 4w) = 0
(72w + 44w2 + 4w3) = 0

Solving
72w + 44w2 + 4w3 = 0
