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

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

Multiply (5 + 3v) * (3 + v)
(5(3 + v) + 3v * (3 + v)) = 0
((3 * 5 + v * 5) + 3v * (3 + v)) = 0
((15 + 5v) + 3v * (3 + v)) = 0
(15 + 5v + (3 * 3v + v * 3v)) = 0
(15 + 5v + (9v + 3v2)) = 0

Combine like terms: 5v + 9v = 14v
(15 + 14v + 3v2) = 0
