Solution for (1+u)(3u-8)=0 equation:


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

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

Multiply (1 + u) * (-8 + 3u)
(1(-8 + 3u) + u(-8 + 3u)) = 0
((-8 * 1 + 3u * 1) + u(-8 + 3u)) = 0
((-8 + 3u) + u(-8 + 3u)) = 0
(-8 + 3u + (-8 * u + 3u * u)) = 0
(-8 + 3u + (-8u + 3u2)) = 0

Combine like terms: 3u + -8u = -5u
(-8 + -5u + 3u2) = 0
