Solution for (5v+2)(4+v)=0 equation:


Simplifying
(5v + 2)(4 + v) = 0

Reorder the terms:
(2 + 5v)(4 + v) = 0

Multiply (2 + 5v) * (4 + v)
(2(4 + v) + 5v * (4 + v)) = 0
((4 * 2 + v * 2) + 5v * (4 + v)) = 0
((8 + 2v) + 5v * (4 + v)) = 0
(8 + 2v + (4 * 5v + v * 5v)) = 0
(8 + 2v + (20v + 5v2)) = 0

Combine like terms: 2v + 20v = 22v
(8 + 22v + 5v2) = 0
