(3+v)(2v-1)=0

Solution for (3+v)(2v-1)=0 equation:

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

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

Multiply (3 + v) * (-1 + 2v)
(3(-1 + 2v) + v(-1 + 2v)) = 0
((-1 * 3 + 2v * 3) + v(-1 + 2v)) = 0
((-3 + 6v) + v(-1 + 2v)) = 0
(-3 + 6v + (-1 * v + 2v * v)) = 0
(-3 + 6v + (-1v + 2v2)) = 0

Combine like terms: 6v + -1v = 5v
(-3 + 5v + 2v2) = 0

Solving
-3 + 5v + 2v2 = 0

Solving for variable 'v'.

Factor a trinomial.
(-3 + -1v)(1 + -2v) = 0

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

Simplifying
-3 + -1v = 0

Solving
-3 + -1v = 0

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

Add '3' to each side of the equation.
-3 + 3 + -1v = 0 + 3

Combine like terms: -3 + 3 = 0
0 + -1v = 0 + 3
-1v = 0 + 3

Combine like terms: 0 + 3 = 3
-1v = 3

Divide each side by '-1'.
v = -3

Simplifying
v = -3
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 = {-3, 0.5}
