(2-u)(4u+3)=0

Solution for (2-u)(4u+3)=0 equation:

Simplifying
(2 + -1u)(4u + 3) = 0

Reorder the terms:
(2 + -1u)(3 + 4u) = 0

Multiply (2 + -1u) * (3 + 4u)
(2(3 + 4u) + -1u * (3 + 4u)) = 0
((3 * 2 + 4u * 2) + -1u * (3 + 4u)) = 0
((6 + 8u) + -1u * (3 + 4u)) = 0
(6 + 8u + (3 * -1u + 4u * -1u)) = 0
(6 + 8u + (-3u + -4u2)) = 0

Combine like terms: 8u + -3u = 5u
(6 + 5u + -4u2) = 0

Solving
6 + 5u + -4u2 = 0

Solving for variable 'u'.
