(v+3)(v+6)=0

Solution for (v+3)(v+6)=0 equation:

Simplifying
(v + 3)(v + 6) = 0

Reorder the terms:
(3 + v)(v + 6) = 0

Reorder the terms:
(3 + v)(6 + v) = 0

Multiply (3 + v) * (6 + v)
(3(6 + v) + v(6 + v)) = 0
((6 * 3 + v * 3) + v(6 + v)) = 0
((18 + 3v) + v(6 + v)) = 0
(18 + 3v + (6 * v + v * v)) = 0
(18 + 3v + (6v + v2)) = 0

Combine like terms: 3v + 6v = 9v
(18 + 9v + v2) = 0

Solving
18 + 9v + v2 = 0

Solving for variable 'v'.

Factor a trinomial.
(6 + v)(3 + v) = 0

Subproblem 1
Set the factor '(6 + v)' equal to zero and attempt to solve:

Simplifying
6 + v = 0

Solving
6 + v = 0

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

Add '-6' to each side of the equation.
6 + -6 + v = 0 + -6

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

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

Simplifying
v = -6
Subproblem 2
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
Solution
v = {-6, -3}
