(8v-3)(3v+7)=0

Solution for (8v-3)(3v+7)=0 equation:

Simplifying
(8v + -3)(3v + 7) = 0

Reorder the terms:
(-3 + 8v)(3v + 7) = 0

Reorder the terms:
(-3 + 8v)(7 + 3v) = 0

Multiply (-3 + 8v) * (7 + 3v)
(-3(7 + 3v) + 8v * (7 + 3v)) = 0
((7 * -3 + 3v * -3) + 8v * (7 + 3v)) = 0
((-21 + -9v) + 8v * (7 + 3v)) = 0
(-21 + -9v + (7 * 8v + 3v * 8v)) = 0
(-21 + -9v + (56v + 24v2)) = 0

Combine like terms: -9v + 56v = 47v
(-21 + 47v + 24v2) = 0

Solving
-21 + 47v + 24v2 = 0
