(5v+3)(2+v)=0

Solution for (5v+3)(2+v)=0 equation:

Simplifying
(5v + 3)(2 + v) = 0

Reorder the terms:
(3 + 5v)(2 + v) = 0

Multiply (3 + 5v) * (2 + v)
(3(2 + v) + 5v * (2 + v)) = 0
((2 * 3 + v * 3) + 5v * (2 + v)) = 0
((6 + 3v) + 5v * (2 + v)) = 0
(6 + 3v + (2 * 5v + v * 5v)) = 0
(6 + 3v + (10v + 5v2)) = 0

Combine like terms: 3v + 10v = 13v
(6 + 13v + 5v2) = 0

Solving
6 + 13v + 5v2 = 0

Solving for variable 'v'.

Factor a trinomial.

0 + v = 0 + -2
v = 0 + -2

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

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

Simplifying
3 + 5v = 0

Solving
3 + 5v = 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 + 5v = 0 + -3

Combine like terms: 3 + -3 = 0
0 + 5v = 0 + -3
5v = 0 + -3

Combine like terms: 0 + -3 = -3
5v = -3

Divide each side by '5'.
v = -0.6

Simplifying
v = -0.6
Solution
v = {-2, -0.6}
