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

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

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

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

Multiply (5 + 2v) * (3 + 2v)
(5(3 + 2v) + 2v * (3 + 2v)) = 0
((3 * 5 + 2v * 5) + 2v * (3 + 2v)) = 0
((15 + 10v) + 2v * (3 + 2v)) = 0
(15 + 10v + (3 * 2v + 2v * 2v)) = 0
(15 + 10v + (6v + 4v2)) = 0

Combine like terms: 10v + 6v = 16v
(15 + 16v + 4v2) = 0
