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


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

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

Multiply (4 + v) * (-7 + 4v)
(4(-7 + 4v) + v(-7 + 4v)) = 0
((-7 * 4 + 4v * 4) + v(-7 + 4v)) = 0
((-28 + 16v) + v(-7 + 4v)) = 0
(-28 + 16v + (-7 * v + 4v * v)) = 0
(-28 + 16v + (-7v + 4v2)) = 0

Combine like terms: 16v + -7v = 9v
(-28 + 9v + 4v2) = 0

Solving
-28 + 9v + 4v2 = 0

Solving for variable 'v'.
