(6+u)(3u-2)=0

Solution for (6+u)(3u-2)=0 equation:

Simplifying
(6 + u)(3u + -2) = 0

Reorder the terms:
(6 + u)(-2 + 3u) = 0

Multiply (6 + u) * (-2 + 3u)
(6(-2 + 3u) + u(-2 + 3u)) = 0
((-2 * 6 + 3u * 6) + u(-2 + 3u)) = 0
((-12 + 18u) + u(-2 + 3u)) = 0
(-12 + 18u + (-2 * u + 3u * u)) = 0
(-12 + 18u + (-2u + 3u2)) = 0

Combine like terms: 18u + -2u = 16u
(-12 + 16u + 3u2) = 0

Solving
-12 + 16u + 3u2 = 0

Solving for variable 'u'.
