(2u-3)(5-u)=0

Solution for (2u-3)(5-u)=0 equation:

Simplifying
(2u + -3)(5 + -1u) = 0

Reorder the terms:
(-3 + 2u)(5 + -1u) = 0

Multiply (-3 + 2u) * (5 + -1u)
(-3(5 + -1u) + 2u * (5 + -1u)) = 0
((5 * -3 + -1u * -3) + 2u * (5 + -1u)) = 0
((-15 + 3u) + 2u * (5 + -1u)) = 0
(-15 + 3u + (5 * 2u + -1u * 2u)) = 0
(-15 + 3u + (10u + -2u2)) = 0

Combine like terms: 3u + 10u = 13u
(-15 + 13u + -2u2) = 0

Solving
-15 + 13u + -2u2 = 0

Solving for variable 'u'.

Factor a trinomial.

u = 5

Simplifying
u = 5
Subproblem 2
Set the factor '(3 + -2u)' equal to zero and attempt to solve:

Simplifying
3 + -2u = 0

Solving
3 + -2u = 0

Move all terms containing u to the left, all other terms to the right.

Add '-3' to each side of the equation.
3 + -3 + -2u = 0 + -3

Combine like terms: 3 + -3 = 0
0 + -2u = 0 + -3
-2u = 0 + -3

Combine like terms: 0 + -3 = -3
-2u = -3

Divide each side by '-2'.
u = 1.5

Simplifying
u = 1.5
Solution
u = {5, 1.5}
