-3(v+5)(-v+6)=0

Solution for -3(v+5)(-v+6)=0 equation:

Simplifying
-3(v + 5)(-1v + 6) = 0

Reorder the terms:
-3(5 + v)(-1v + 6) = 0

Reorder the terms:
-3(5 + v)(6 + -1v) = 0

Multiply (5 + v) * (6 + -1v)
-3(5(6 + -1v) + v(6 + -1v)) = 0
-3((6 * 5 + -1v * 5) + v(6 + -1v)) = 0
-3((30 + -5v) + v(6 + -1v)) = 0
-3(30 + -5v + (6 * v + -1v * v)) = 0
-3(30 + -5v + (6v + -1v2)) = 0

Combine like terms: -5v + 6v = 1v
-3(30 + 1v + -1v2) = 0
(30 * -3 + 1v * -3 + -1v2 * -3) = 0
(-90 + -3v + 3v2) = 0

Solving
-90 + -3v + 3v2 = 0

Solving for variable 'v'.

Factor out the Greatest Common Factor (GCF), '3'.

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 '(6 + -1v)' equal to zero and attempt to solve:

Simplifying
6 + -1v = 0

Solving
6 + -1v = 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 + -1v = 0 + -6

Combine like terms: 6 + -6 = 0
0 + -1v = 0 + -6
-1v = 0 + -6

Combine like terms: 0 + -6 = -6
-1v = -6

Divide each side by '-1'.
v = 6

Simplifying
v = 6
Solution
v = {-5, 6}
