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

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

Simplifying
(2 + -1v)(5v + 3) = 0

Reorder the terms:
(2 + -1v)(3 + 5v) = 0

Multiply (2 + -1v) * (3 + 5v)
(2(3 + 5v) + -1v * (3 + 5v)) = 0
((3 * 2 + 5v * 2) + -1v * (3 + 5v)) = 0
((6 + 10v) + -1v * (3 + 5v)) = 0
(6 + 10v + (3 * -1v + 5v * -1v)) = 0
(6 + 10v + (-3v + -5v2)) = 0

Combine like terms: 10v + -3v = 7v
(6 + 7v + -5v2) = 0

Solving
6 + 7v + -5v2 = 0

Solving for variable 'v'.
