(v+1)(v-6)=0

Solution for (v+1)(v-6)=0 equation:

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

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

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

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

Combine like terms: 1v + -6v = -5v
(-6 + -5v + v2) = 0

Solving
-6 + -5v + v2 = 0

Solving for variable 'v'.

Factor a trinomial.
(-1 + -1v)(6 + -1v) = 0

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

Simplifying
-1 + -1v = 0

Solving
-1 + -1v = 0

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

Add '1' to each side of the equation.
-1 + 1 + -1v = 0 + 1

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

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

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

Simplifying
v = -1
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 = {-1, 6}
