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

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

Simplifying
(v + 5)(v + -5) = 0

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

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

Multiply (5 + v) * (-5 + v)
(5(-5 + v) + v(-5 + v)) = 0
((-5 * 5 + v * 5) + v(-5 + v)) = 0
((-25 + 5v) + v(-5 + v)) = 0
(-25 + 5v + (-5 * v + v * v)) = 0
(-25 + 5v + (-5v + v2)) = 0

Combine like terms: 5v + -5v = 0
(-25 + 0 + v2) = 0
(-25 + v2) = 0

Solving
-25 + v2 = 0

Solving for variable 'v'.

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

Add '25' to each side of the equation.
-25 + 25 + v2 = 0 + 25

Combine like terms: -25 + 25 = 0
0 + v2 = 0 + 25
v2 = 0 + 25

Combine like terms: 0 + 25 = 25
v2 = 25

Simplifying
v2 = 25

Take the square root of each side:
v = {-5, 5}
