(6+v)(2v+5)=0

Solution for (6+v)(2v+5)=0 equation:

Simplifying
(6 + v)(2v + 5) = 0

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

Multiply (6 + v) * (5 + 2v)
(6(5 + 2v) + v(5 + 2v)) = 0
((5 * 6 + 2v * 6) + v(5 + 2v)) = 0
((30 + 12v) + v(5 + 2v)) = 0
(30 + 12v + (5 * v + 2v * v)) = 0
(30 + 12v + (5v + 2v2)) = 0

Combine like terms: 12v + 5v = 17v
(30 + 17v + 2v2) = 0

Solving
30 + 17v + 2v2 = 0

Solving for variable 'v'.

Factor a trinomial.

0 + v = 0 + -6
v = 0 + -6

Combine like terms: 0 + -6 = -6
v = -6

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

Simplifying
5 + 2v = 0

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

Combine like terms: 5 + -5 = 0
0 + 2v = 0 + -5
2v = 0 + -5

Combine like terms: 0 + -5 = -5
2v = -5

Divide each side by '2'.
v = -2.5

Simplifying
v = -2.5
Solution
v = {-6, -2.5}
