(v+4)(v-4)=

Solution for (v+4)(v-4)= equation:

Simplifying
(v + 4)(v + -4) = 0

Reorder the terms:
(4 + v)(v + -4) = 0

Reorder the terms:
(4 + v)(-4 + v) = 0

Multiply (4 + v) * (-4 + v)
(4(-4 + v) + v(-4 + v)) = 0
((-4 * 4 + v * 4) + v(-4 + v)) = 0
((-16 + 4v) + v(-4 + v)) = 0
(-16 + 4v + (-4 * v + v * v)) = 0
(-16 + 4v + (-4v + v2)) = 0

Combine like terms: 4v + -4v = 0
(-16 + 0 + v2) = 0
(-16 + v2) = 0

Solving
-16 + v2 = 0

Solving for variable 'v'.

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

Add '16' to each side of the equation.
-16 + 16 + v2 = 0 + 16

Combine like terms: -16 + 16 = 0
0 + v2 = 0 + 16
v2 = 0 + 16

Combine like terms: 0 + 16 = 16
v2 = 16

Simplifying
v2 = 16

Take the square root of each side:
v = {-4, 4}
