Solution for (2v-5)(v+3)=0 equation:


Simplifying
(2v + -5)(v + 3) = 0

Reorder the terms:
(-5 + 2v)(v + 3) = 0

Reorder the terms:
(-5 + 2v)(3 + v) = 0

Multiply (-5 + 2v) * (3 + v)
(-5(3 + v) + 2v * (3 + v)) = 0
((3 * -5 + v * -5) + 2v * (3 + v)) = 0
((-15 + -5v) + 2v * (3 + v)) = 0
(-15 + -5v + (3 * 2v + v * 2v)) = 0
(-15 + -5v + (6v + 2v2)) = 0

Combine like terms: -5v + 6v = 1v
(-15 + 1v + 2v2) = 0

Solving
-15 + 1v + 2v2 = 0

Solving for variable 'v'.

Factor a trinomial.
