Simplifying
(8 + u)(3u + -4) = 0

Reorder the terms:
(8 + u)(-4 + 3u) = 0

Multiply (8 + u) * (-4 + 3u)
(8(-4 + 3u) + u(-4 + 3u)) = 0
((-4 * 8 + 3u * 8) + u(-4 + 3u)) = 0
((-32 + 24u) + u(-4 + 3u)) = 0
(-32 + 24u + (-4 * u + 3u * u)) = 0
(-32 + 24u + (-4u + 3u2)) = 0

Combine like terms: 24u + -4u = 20u
(-32 + 20u + 3u2) = 0
