Solution for (3v-4)(5-v)=0 equation:


Simplifying
(3v + -4)(5 + -1v) = 0

Reorder the terms:
(-4 + 3v)(5 + -1v) = 0

Multiply (-4 + 3v) * (5 + -1v)
(-4(5 + -1v) + 3v * (5 + -1v)) = 0
((5 * -4 + -1v * -4) + 3v * (5 + -1v)) = 0
((-20 + 4v) + 3v * (5 + -1v)) = 0
(-20 + 4v + (5 * 3v + -1v * 3v)) = 0
(-20 + 4v + (15v + -3v2)) = 0

Combine like terms: 4v + 15v = 19v
(-20 + 19v + -3v2) = 0

Solving
-20 + 19v + -3v2 = 0
