Solution for (3v+5)(v+2)=0 equation:


Simplifying
(3v + 5)(v + 2) = 0

Reorder the terms:
(5 + 3v)(v + 2) = 0

Reorder the terms:
(5 + 3v)(2 + v) = 0

Multiply (5 + 3v) * (2 + v)
(5(2 + v) + 3v * (2 + v)) = 0
((2 * 5 + v * 5) + 3v * (2 + v)) = 0
((10 + 5v) + 3v * (2 + v)) = 0
(10 + 5v + (2 * 3v + v * 3v)) = 0
(10 + 5v + (6v + 3v2)) = 0

Combine like terms: 5v + 6v = 11v
(10 + 11v + 3v2) = 0
