Solution for (3v+8)(4+v)=0 equation:


Simplifying
(3v + 8)(4 + v) = 0

Reorder the terms:
(8 + 3v)(4 + v) = 0

Multiply (8 + 3v) * (4 + v)
(8(4 + v) + 3v * (4 + v)) = 0
((4 * 8 + v * 8) + 3v * (4 + v)) = 0
((32 + 8v) + 3v * (4 + v)) = 0
(32 + 8v + (4 * 3v + v * 3v)) = 0
(32 + 8v + (12v + 3v2)) = 0

Combine like terms: 8v + 12v = 20v
(32 + 20v + 3v2) = 0

Solving
32 + 20v + 3v2 = 0
