Solution for (2v+9)(5+v)=0 equation:


Simplifying
(2v + 9)(5 + v) = 0

Reorder the terms:
(9 + 2v)(5 + v) = 0

Multiply (9 + 2v) * (5 + v)
(9(5 + v) + 2v * (5 + v)) = 0
((5 * 9 + v * 9) + 2v * (5 + v)) = 0
((45 + 9v) + 2v * (5 + v)) = 0
(45 + 9v + (5 * 2v + v * 2v)) = 0
(45 + 9v + (10v + 2v2)) = 0

Combine like terms: 9v + 10v = 19v
(45 + 19v + 2v2) = 0
