Solution for (6-v)(3v+7)=0 equation:


Simplifying
(6 + -1v)(3v + 7) = 0

Reorder the terms:
(6 + -1v)(7 + 3v) = 0

Multiply (6 + -1v) * (7 + 3v)
(6(7 + 3v) + -1v * (7 + 3v)) = 0
((7 * 6 + 3v * 6) + -1v * (7 + 3v)) = 0
((42 + 18v) + -1v * (7 + 3v)) = 0
(42 + 18v + (7 * -1v + 3v * -1v)) = 0
(42 + 18v + (-7v + -3v2)) = 0

Combine like terms: 18v + -7v = 11v
(42 + 11v + -3v2) = 0
