(v-5)(v+5)=

Solution for (v-5)(v+5)= 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}
