(4v+2)(3+v)=0

Solution for (4v+2)(3+v)=0 equation:

Simplifying
(4v + 2)(3 + v) = 0

Reorder the terms:
(2 + 4v)(3 + v) = 0

Multiply (2 + 4v) * (3 + v)
(2(3 + v) + 4v * (3 + v)) = 0
((3 * 2 + v * 2) + 4v * (3 + v)) = 0
((6 + 2v) + 4v * (3 + v)) = 0
(6 + 2v + (3 * 4v + v * 4v)) = 0
(6 + 2v + (12v + 4v2)) = 0

Combine like terms: 2v + 12v = 14v
(6 + 14v + 4v2) = 0

Solving
6 + 14v + 4v2 = 0

Solving for variable 'v'.

Factor out the Greatest Common Factor (GCF), '2'.
2(3 + 7v + 2v2) = 0

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

Ignore the factor 2.
Subproblem 1
Set the factor '(3 + v)' equal to zero and attempt to solve:

Simplifying
3 + v = 0

Solving
3 + v = 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 + v = 0 + -3

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

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