(3u-4)(1-u)=0

Solution for (3u-4)(1-u)=0 equation:

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

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

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

Combine like terms: 4u + 3u = 7u
(-4 + 7u + -3u2) = 0

Solving
-4 + 7u + -3u2 = 0

Solving for variable 'u'.
