(4v+6)(5-v)=0

Solution for (4v+6)(5-v)=0 equation:

Simplifying
(4v + 6)(5 + -1v) = 0

Reorder the terms:
(6 + 4v)(5 + -1v) = 0

Multiply (6 + 4v) * (5 + -1v)
(6(5 + -1v) + 4v * (5 + -1v)) = 0
((5 * 6 + -1v * 6) + 4v * (5 + -1v)) = 0
((30 + -6v) + 4v * (5 + -1v)) = 0
(30 + -6v + (5 * 4v + -1v * 4v)) = 0
(30 + -6v + (20v + -4v2)) = 0

Combine like terms: -6v + 20v = 14v
(30 + 14v + -4v2) = 0

Solving
30 + 14v + -4v2 = 0

Solving for variable 'v'.

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

Simplifying
5 + -1v = 0

Solving
5 + -1v = 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 + -1v = 0 + -5

Combine like terms: 5 + -5 = 0
0 + -1v = 0 + -5
-1v = 0 + -5

Combine like terms: 0 + -5 = -5
-1v = -5

Divide each side by '-1'.
v = 5

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

Simplifying
3 + 2v = 0

Solving
3 + 2v = 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 + 2v = 0 + -3

Combine like terms: 3 + -3 = 0
0 + 2v = 0 + -3
2v = 0 + -3

Combine like terms: 0 + -3 = -3
2v = -3

Divide each side by '2'.
v = -1.5

Simplifying
v = -1.5
Solution
v = {5, -1.5}
