Solution for (5+v)(3v-4)=0 equation:


Simplifying
(5 + v)(3v + -4) = 0

Reorder the terms:
(5 + v)(-4 + 3v) = 0

Multiply (5 + v) * (-4 + 3v)
(5(-4 + 3v) + v(-4 + 3v)) = 0
((-4 * 5 + 3v * 5) + v(-4 + 3v)) = 0
((-20 + 15v) + v(-4 + 3v)) = 0
(-20 + 15v + (-4 * v + 3v * v)) = 0
(-20 + 15v + (-4v + 3v2)) = 0

Combine like terms: 15v + -4v = 11v
(-20 + 11v + 3v2) = 0

Solving
-20 + 11v + 3v2 = 0
