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

Solution for (5u+2)(1-u)=0 equation:

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

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

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

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

Solving
2 + 3u + -5u2 = 0

Solving for variable 'u'.

2 + -2 + 5u = 0 + -2

Combine like terms: 2 + -2 = 0
0 + 5u = 0 + -2
5u = 0 + -2

Combine like terms: 0 + -2 = -2
5u = -2

Divide each side by '5'.
u = -0.4

Simplifying
u = -0.4
Solution
u = {1, -0.4}
