Reorder the terms:
(5 + 4w)(2 + -1w) = 0

Multiply (5 + 4w) * (2 + -1w)
(5(2 + -1w) + 4w * (2 + -1w)) = 0
((2 * 5 + -1w * 5) + 4w * (2 + -1w)) = 0
((10 + -5w) + 4w * (2 + -1w)) = 0
(10 + -5w + (2 * 4w + -1w * 4w)) = 0
(10 + -5w + (8w + -4w2)) = 0

Combine like terms: -5w + 8w = 3w
(10 + 3w + -4w2) = 0
