4w(-6 + w)(7 + w) = 0

Multiply (-6 + w) * (7 + w)
4w(-6(7 + w) + w(7 + w)) = 0
4w((7 * -6 + w * -6) + w(7 + w)) = 0
4w((-42 + -6w) + w(7 + w)) = 0
4w(-42 + -6w + (7 * w + w * w)) = 0
4w(-42 + -6w + (7w + w2)) = 0

Combine like terms: -6w + 7w = 1w
4w(-42 + 1w + w2) = 0
(-42 * 4w + 1w * 4w + w2 * 4w) = 0
(-168w + 4w2 + 4w3) = 0

Solving
-168w + 4w2 + 4w3 = 0

Solving for variable 'w'.
