Solution for (v+7)(v-4)=0 equation: 


Simplifying
(v + 7)(v + -4) = 0

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

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

Multiply (7 + v) * (-4 + v)
(7(-4 + v) + v(-4 + v)) = 0
((-4 * 7 + v * 7) + v(-4 + v)) = 0
((-28 + 7v) + v(-4 + v)) = 0
(-28 + 7v + (-4 * v + v * v)) = 0
(-28 + 7v + (-4v + v2)) = 0

Combine like terms: 7v + -4v = 3v
(-28 + 3v + v2) = 0

Solving
-28 + 3v + v2 = 0
