(5v+6)(1+v)=0

Solution for (5v+6)(1+v)=0 equation:

Simplifying
(5v + 6)(1 + v) = 0

Reorder the terms:
(6 + 5v)(1 + v) = 0

Multiply (6 + 5v) * (1 + v)
(6(1 + v) + 5v * (1 + v)) = 0
((1 * 6 + v * 6) + 5v * (1 + v)) = 0
((6 + 6v) + 5v * (1 + v)) = 0
(6 + 6v + (1 * 5v + v * 5v)) = 0
(6 + 6v + (5v + 5v2)) = 0

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

Solving
6 + 11v + 5v2 = 0

Solving for variable 'v'.
