2v^2+9v-12=0

a = 2; b = 9; c = -12;
Δ = b2-4ac
Δ = 92-4·2·(-12)
Δ = 177
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$v_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$v_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$v_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(9)-\sqrt{177}}{2*2}=\frac{-9-\sqrt{177}}{4}
$


$v_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(9)+\sqrt{177}}{2*2}=\frac{-9+\sqrt{177}}{4}
$
