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

Solution for (5u+3)(1-u)=0 equation:

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

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

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

Combine like terms: -3u + 5u = 2u
(3 + 2u + -5u2) = 0

Solving
3 + 2u + -5u2 = 0

Solving for variable 'u'.

3 + -3 + 5u = 0 + -3

Combine like terms: 3 + -3 = 0
0 + 5u = 0 + -3
5u = 0 + -3

Combine like terms: 0 + -3 = -3
5u = -3

Divide each side by '5'.
u = -0.6

Simplifying
u = -0.6
Solution
u = {1, -0.6}
