(5u-8)(6-u)=0

Solution for (5u-8)(6-u)=0 equation:

Simplifying
(5u + -8)(6 + -1u) = 0

Reorder the terms:
(-8 + 5u)(6 + -1u) = 0

Multiply (-8 + 5u) * (6 + -1u)
(-8(6 + -1u) + 5u * (6 + -1u)) = 0
((6 * -8 + -1u * -8) + 5u * (6 + -1u)) = 0
((-48 + 8u) + 5u * (6 + -1u)) = 0
(-48 + 8u + (6 * 5u + -1u * 5u)) = 0
(-48 + 8u + (30u + -5u2)) = 0

Combine like terms: 8u + 30u = 38u
(-48 + 38u + -5u2) = 0

Solving
-48 + 38u + -5u2 = 0

Solving for variable 'u'.
