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
