Solution for (3v+1)(9+v)=0 equation:


Simplifying
(3v + 1)(9 + v) = 0

Reorder the terms:
(1 + 3v)(9 + v) = 0

Multiply (1 + 3v) * (9 + v)
(1(9 + v) + 3v * (9 + v)) = 0
((9 * 1 + v * 1) + 3v * (9 + v)) = 0
((9 + 1v) + 3v * (9 + v)) = 0
(9 + 1v + (9 * 3v + v * 3v)) = 0
(9 + 1v + (27v + 3v2)) = 0

Combine like terms: 1v + 27v = 28v
(9 + 28v + 3v2) = 0

Solving
9 + 28v + 3v2 = 0

Solving for variable 'v'.

Factor a trinomial.
