(6-v)(3v+5)=0

Solution for (6-v)(3v+5)=0 equation:

Simplifying
(6 + -1v)(3v + 5) = 0

Reorder the terms:
(6 + -1v)(5 + 3v) = 0

Multiply (6 + -1v) * (5 + 3v)
(6(5 + 3v) + -1v * (5 + 3v)) = 0
((5 * 6 + 3v * 6) + -1v * (5 + 3v)) = 0
((30 + 18v) + -1v * (5 + 3v)) = 0
(30 + 18v + (5 * -1v + 3v * -1v)) = 0
(30 + 18v + (-5v + -3v2)) = 0

Combine like terms: 18v + -5v = 13v
(30 + 13v + -3v2) = 0

Solving
30 + 13v + -3v2 = 0

Solving for variable 'v'.
