Solution for (4v+3)(v+5)=0 equation:


Simplifying
(4v + 3)(v + 5) = 0

Reorder the terms:
(3 + 4v)(v + 5) = 0

Reorder the terms:
(3 + 4v)(5 + v) = 0

Multiply (3 + 4v) * (5 + v)
(3(5 + v) + 4v * (5 + v)) = 0
((5 * 3 + v * 3) + 4v * (5 + v)) = 0
((15 + 3v) + 4v * (5 + v)) = 0
(15 + 3v + (5 * 4v + v * 4v)) = 0
(15 + 3v + (20v + 4v2)) = 0

Combine like terms: 3v + 20v = 23v
(15 + 23v + 4v2) = 0

Solving
15 + 23v + 4v2 = 0
