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

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

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

Multiply (3 + -1u) * (2 + 3u)
(3(2 + 3u) + -1u * (2 + 3u)) = 0
((2 * 3 + 3u * 3) + -1u * (2 + 3u)) = 0
((6 + 9u) + -1u * (2 + 3u)) = 0
(6 + 9u + (2 * -1u + 3u * -1u)) = 0
(6 + 9u + (-2u + -3u2)) = 0

Combine like terms: 9u + -2u = 7u
(6 + 7u + -3u2) = 0

Solving
6 + 7u + -3u2 = 0

Solving for variable 'u'.
