Solution for (3u-2)(5-u)=0 equation:


Simplifying
(3u + -2)(5 + -1u) = 0

Reorder the terms:
(-2 + 3u)(5 + -1u) = 0

Multiply (-2 + 3u) * (5 + -1u)
(-2(5 + -1u) + 3u * (5 + -1u)) = 0
((5 * -2 + -1u * -2) + 3u * (5 + -1u)) = 0
((-10 + 2u) + 3u * (5 + -1u)) = 0
(-10 + 2u + (5 * 3u + -1u * 3u)) = 0
(-10 + 2u + (15u + -3u2)) = 0

Combine like terms: 2u + 15u = 17u
(-10 + 17u + -3u2) = 0
