(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}
