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

Solution for (6-u)(5u-3)=0 equation:

Simplifying
(6 + -1u)(5u + -3) = 0

Reorder the terms:
(6 + -1u)(-3 + 5u) = 0

Multiply (6 + -1u) * (-3 + 5u)
(6(-3 + 5u) + -1u * (-3 + 5u)) = 0
((-3 * 6 + 5u * 6) + -1u * (-3 + 5u)) = 0
((-18 + 30u) + -1u * (-3 + 5u)) = 0
(-18 + 30u + (-3 * -1u + 5u * -1u)) = 0
(-18 + 30u + (3u + -5u2)) = 0

Combine like terms: 30u + 3u = 33u
(-18 + 33u + -5u2) = 0

Solving
-18 + 33u + -5u2 = 0

Solving for variable 'u'.

Factor a trinomial.

u = 6
Subproblem 2
Set the factor '(3 + -5u)' equal to zero and attempt to solve:

Simplifying
3 + -5u = 0

Solving
3 + -5u = 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 + -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 = {6, 0.6}
