Solution for (v+5)(v-9)=0 equation:


Simplifying
(v + 5)(v + -9) = 0

Reorder the terms:
(5 + v)(v + -9) = 0

Reorder the terms:
(5 + v)(-9 + v) = 0

Multiply (5 + v) * (-9 + v)
(5(-9 + v) + v(-9 + v)) = 0
((-9 * 5 + v * 5) + v(-9 + v)) = 0
((-45 + 5v) + v(-9 + v)) = 0
(-45 + 5v + (-9 * v + v * v)) = 0
(-45 + 5v + (-9v + v2)) = 0

Combine like terms: 5v + -9v = -4v
(-45 + -4v + v2) = 0

Solving
-45 + -4v + v2 = 0

Solving for variable 'v'.
