2v^2-13v-24=0

Solution for 2v^2-13v-24=0 equation:

2v^2-13v-24=0

a = 2; b = -13; c = -24;
Δ = b2-4ac
Δ = -132-4·2·(-24)
Δ = 361
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$v_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$v_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{361}=19$
$v_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-13)-19}{2*2}=\frac{-6}{4}
=-1+1/2
$
$v_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-13)+19}{2*2}=\frac{32}{4}
=8
