(2v-1)(5-v)=0

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

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

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

Multiply (-1 + 2v) * (5 + -1v)
(-1(5 + -1v) + 2v * (5 + -1v)) = 0
((5 * -1 + -1v * -1) + 2v * (5 + -1v)) = 0
((-5 + 1v) + 2v * (5 + -1v)) = 0
(-5 + 1v + (5 * 2v + -1v * 2v)) = 0
(-5 + 1v + (10v + -2v2)) = 0

Combine like terms: 1v + 10v = 11v
(-5 + 11v + -2v2) = 0

Solving
-5 + 11v + -2v2 = 0

Solving for variable 'v'.

Factor a trinomial.
(-5 + v)(1 + -2v) = 0

Subproblem 1
Set the factor '(-5 + v)' equal to zero and attempt to solve:

Simplifying
-5 + v = 0

Solving
-5 + v = 0

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

Add '5' to each side of the equation.
-5 + 5 + v = 0 + 5

Combine like terms: -5 + 5 = 0
0 + v = 0 + 5
v = 0 + 5

Combine like terms: 0 + 5 = 5
v = 5

Simplifying
v = 5
Subproblem 2
Set the factor '(1 + -2v)' equal to zero and attempt to solve:

Simplifying
1 + -2v = 0

Solving
1 + -2v = 0

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

Add '-1' to each side of the equation.
1 + -1 + -2v = 0 + -1

Combine like terms: 1 + -1 = 0
0 + -2v = 0 + -1
-2v = 0 + -1

Combine like terms: 0 + -1 = -1
-2v = -1

Divide each side by '-2'.
v = 0.5

Simplifying
v = 0.5
Solution
v = {5, 0.5}
