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


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

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

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

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

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

Solving
-16 + v2 = x

Solving for variable 'v'.

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