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

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

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

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

Multiply (3 + -1u) * (-2 + 5u)
(3(-2 + 5u) + -1u * (-2 + 5u)) = 0
((-2 * 3 + 5u * 3) + -1u * (-2 + 5u)) = 0
((-6 + 15u) + -1u * (-2 + 5u)) = 0
(-6 + 15u + (-2 * -1u + 5u * -1u)) = 0
(-6 + 15u + (2u + -5u2)) = 0

Combine like terms: 15u + 2u = 17u
(-6 + 17u + -5u2) = 0

Solving
-6 + 17u + -5u2 = 0

Solving for variable 'u'.

Factor a trinomial.
(-3 + u)(2 + -5u) = 0

Subproblem 1
Set the factor '(-3 + u)' equal to zero and attempt to solve:

Simplifying
-3 + u = 0

Solving
-3 + u = 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 + u = 0 + 3

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

u = 3

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

Simplifying
2 + -5u = 0

Solving
2 + -5u = 0

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

Add '-2' to each side of the equation.
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 = {3, 0.4}
