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


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

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

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

Multiply (3 + v) * (-3 + 5v)
(3(-3 + 5v) + v(-3 + 5v)) = 0
((-3 * 3 + 5v * 3) + v(-3 + 5v)) = 0
((-9 + 15v) + v(-3 + 5v)) = 0
(-9 + 15v + (-3 * v + 5v * v)) = 0
(-9 + 15v + (-3v + 5v2)) = 0

Combine like terms: 15v + -3v = 12v
(-9 + 12v + 5v2) = 0

Solving
-9 + 12v + 5v2 = 0
