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

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

Multiply (7 + w) * (-4 + 3w)
(7(-4 + 3w) + w(-4 + 3w)) = 0
((-4 * 7 + 3w * 7) + w(-4 + 3w)) = 0
((-28 + 21w) + w(-4 + 3w)) = 0
(-28 + 21w + (-4 * w + 3w * w)) = 0
(-28 + 21w + (-4w + 3w2)) = 0

Combine like terms: 21w + -4w = 17w
(-28 + 17w + 3w2) = 0
