Simplifying
(3 + -1v)(3v + 8) = 0

Reorder the terms:
(3 + -1v)(8 + 3v) = 0

Multiply (3 + -1v) * (8 + 3v)
(3(8 + 3v) + -1v * (8 + 3v)) = 0
((8 * 3 + 3v * 3) + -1v * (8 + 3v)) = 0
((24 + 9v) + -1v * (8 + 3v)) = 0
(24 + 9v + (8 * -1v + 3v * -1v)) = 0
(24 + 9v + (-8v + -3v2)) = 0

Combine like terms: 9v + -8v = 1v
(24 + 1v + -3v2) = 0
