Solution for (4+v)(2v-7)=0 equation: 


Simplifying
(4 + v)(2v + -7) = 0

Reorder the terms:
(4 + v)(-7 + 2v) = 0

Multiply (4 + v) * (-7 + 2v)
(4(-7 + 2v) + v(-7 + 2v)) = 0
((-7 * 4 + 2v * 4) + v(-7 + 2v)) = 0
((-28 + 8v) + v(-7 + 2v)) = 0
(-28 + 8v + (-7 * v + 2v * v)) = 0
(-28 + 8v + (-7v + 2v2)) = 0

Combine like terms: 8v + -7v = 1v
(-28 + 1v + 2v2) = 0

Solving
-28 + 1v + 2v2 = 0

Solving for variable 'v'.
