Simplifying
(5w + 1)(w + 8) = 0

Reorder the terms:
(1 + 5w)(w + 8) = 0

Reorder the terms:
(1 + 5w)(8 + w) = 0

Multiply (1 + 5w) * (8 + w)
(1(8 + w) + 5w * (8 + w)) = 0
((8 * 1 + w * 1) + 5w * (8 + w)) = 0
((8 + 1w) + 5w * (8 + w)) = 0
(8 + 1w + (8 * 5w + w * 5w)) = 0
(8 + 1w + (40w + 5w2)) = 0

Combine like terms: 1w + 40w = 41w
(8 + 41w + 5w2) = 0
