Solution for (v+7)(v-12)=0 equation: 


Simplifying
(v + 7)(v + -12) = 0

Reorder the terms:
(7 + v)(v + -12) = 0

Reorder the terms:
(7 + v)(-12 + v) = 0

Multiply (7 + v) * (-12 + v)
(7(-12 + v) + v(-12 + v)) = 0
((-12 * 7 + v * 7) + v(-12 + v)) = 0
((-84 + 7v) + v(-12 + v)) = 0
(-84 + 7v + (-12 * v + v * v)) = 0
(-84 + 7v + (-12v + v2)) = 0

Combine like terms: 7v + -12v = -5v
(-84 + -5v + v2) = 0

Solving
-84 + -5v + v2 = 0
