(6-u)(3u+4)=0

Solution for (6-u)(3u+4)=0 equation:

Simplifying
(6 + -1u)(3u + 4) = 0

Reorder the terms:
(6 + -1u)(4 + 3u) = 0

Multiply (6 + -1u) * (4 + 3u)
(6(4 + 3u) + -1u * (4 + 3u)) = 0
((4 * 6 + 3u * 6) + -1u * (4 + 3u)) = 0
((24 + 18u) + -1u * (4 + 3u)) = 0
(24 + 18u + (4 * -1u + 3u * -1u)) = 0
(24 + 18u + (-4u + -3u2)) = 0

Combine like terms: 18u + -4u = 14u
(24 + 14u + -3u2) = 0

Solving
24 + 14u + -3u2 = 0
