Simplifying
5u(u + 4)(u + 3) = 0

Reorder the terms:
5u(4 + u)(u + 3) = 0

Reorder the terms:
5u(4 + u)(3 + u) = 0

Multiply (4 + u) * (3 + u)
5u(4(3 + u) + u(3 + u)) = 0
5u((3 * 4 + u * 4) + u(3 + u)) = 0
5u((12 + 4u) + u(3 + u)) = 0
5u(12 + 4u + (3 * u + u * u)) = 0
5u(12 + 4u + (3u + u2)) = 0

Combine like terms: 4u + 3u = 7u
5u(12 + 7u + u2) = 0
(12 * 5u + 7u * 5u + u2 * 5u) = 0
(60u + 35u2 + 5u3) = 0

Solving
60u + 35u2 + 5u3 = 0
