Solution for (v+2)(v-8)=0 equation: 


Simplifying
(v + 2)(v + -8) = 0

Reorder the terms:
(2 + v)(v + -8) = 0

Reorder the terms:
(2 + v)(-8 + v) = 0

Multiply (2 + v) * (-8 + v)
(2(-8 + v) + v(-8 + v)) = 0
((-8 * 2 + v * 2) + v(-8 + v)) = 0
((-16 + 2v) + v(-8 + v)) = 0
(-16 + 2v + (-8 * v + v * v)) = 0
(-16 + 2v + (-8v + v2)) = 0

Combine like terms: 2v + -8v = -6v
(-16 + -6v + v2) = 0

Solving
-16 + -6v + v2 = 0

Solving for variable 'v'.
