Solution for (3v+7)(4v-3)= equation:


Simplifying
(3v + 7)(4v + -3) = 0

Reorder the terms:
(7 + 3v)(4v + -3) = 0

Reorder the terms:
(7 + 3v)(-3 + 4v) = 0

Multiply (7 + 3v) * (-3 + 4v)
(7(-3 + 4v) + 3v * (-3 + 4v)) = 0
((-3 * 7 + 4v * 7) + 3v * (-3 + 4v)) = 0
((-21 + 28v) + 3v * (-3 + 4v)) = 0
(-21 + 28v + (-3 * 3v + 4v * 3v)) = 0
(-21 + 28v + (-9v + 12v2)) = 0

Combine like terms: 28v + -9v = 19v
(-21 + 19v + 12v2) = 0

Solving
-21 + 19v + 12v2 = 0
