(v+2)(v-2)=0

Solution for (v+2)(v-2)=0 equation:

Simplifying
(v + 2)(v + -2) = 0

Reorder the terms:
(2 + v)(v + -2) = 0

Reorder the terms:
(2 + v)(-2 + v) = 0

Multiply (2 + v) * (-2 + v)
(2(-2 + v) + v(-2 + v)) = 0
((-2 * 2 + v * 2) + v(-2 + v)) = 0
((-4 + 2v) + v(-2 + v)) = 0
(-4 + 2v + (-2 * v + v * v)) = 0
(-4 + 2v + (-2v + v2)) = 0

Combine like terms: 2v + -2v = 0
(-4 + 0 + v2) = 0
(-4 + v2) = 0

Solving
-4 + v2 = 0

Solving for variable 'v'.

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

Add '4' to each side of the equation.
-4 + 4 + v2 = 0 + 4

Combine like terms: -4 + 4 = 0
0 + v2 = 0 + 4
v2 = 0 + 4

Combine like terms: 0 + 4 = 4
v2 = 4

Simplifying
v2 = 4

Take the square root of each side:
v = {-2, 2}
