(v-3)(v+3)=

Solution for (v-3)(v+3)= equation:

Simplifying
(v + -3)(v + 3) = 0

Reorder the terms:
(-3 + v)(v + 3) = 0

Reorder the terms:
(-3 + v)(3 + v) = 0

Multiply (-3 + v) * (3 + v)
(-3(3 + v) + v(3 + v)) = 0
((3 * -3 + v * -3) + v(3 + v)) = 0
((-9 + -3v) + v(3 + v)) = 0
(-9 + -3v + (3 * v + v * v)) = 0
(-9 + -3v + (3v + v2)) = 0

Combine like terms: -3v + 3v = 0
(-9 + 0 + v2) = 0
(-9 + v2) = 0

Solving
-9 + v2 = 0

Solving for variable 'v'.

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

Add '9' to each side of the equation.
-9 + 9 + v2 = 0 + 9

Combine like terms: -9 + 9 = 0
0 + v2 = 0 + 9
v2 = 0 + 9

Combine like terms: 0 + 9 = 9
v2 = 9

Simplifying
v2 = 9

Take the square root of each side:
v = {-3, 3}
