Solution for (4u-2)(9-u)=0 equation:


Simplifying
(4u + -2)(9 + -1u) = 0

Reorder the terms:
(-2 + 4u)(9 + -1u) = 0

Multiply (-2 + 4u) * (9 + -1u)
(-2(9 + -1u) + 4u * (9 + -1u)) = 0
((9 * -2 + -1u * -2) + 4u * (9 + -1u)) = 0
((-18 + 2u) + 4u * (9 + -1u)) = 0
(-18 + 2u + (9 * 4u + -1u * 4u)) = 0
(-18 + 2u + (36u + -4u2)) = 0
