(v-10)(v+10)=

Solution for (v-10)(v+10)= equation:

Simplifying
(v + -10)(v + 10) = 0

Reorder the terms:
(-10 + v)(v + 10) = 0

Reorder the terms:
(-10 + v)(10 + v) = 0

Multiply (-10 + v) * (10 + v)
(-10(10 + v) + v(10 + v)) = 0
((10 * -10 + v * -10) + v(10 + v)) = 0
((-100 + -10v) + v(10 + v)) = 0
(-100 + -10v + (10 * v + v * v)) = 0
(-100 + -10v + (10v + v2)) = 0

Combine like terms: -10v + 10v = 0
(-100 + 0 + v2) = 0
(-100 + v2) = 0

Solving
-100 + v2 = 0

Solving for variable 'v'.

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

Add '100' to each side of the equation.
-100 + 100 + v2 = 0 + 100

Combine like terms: -100 + 100 = 0
0 + v2 = 0 + 100
v2 = 0 + 100

Combine like terms: 0 + 100 = 100
v2 = 100

Simplifying
v2 = 100

Take the square root of each side:
v = {-10, 10}
