7k^2+3k-2=0

a = 7; b = 3; c = -2;
Δ = b2-4ac
Δ = 32-4·7·(-2)
Δ = 65
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$k_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$k_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$k_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(3)-\sqrt{65}}{2*7}=\frac{-3-\sqrt{65}}{14}
$


$k_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(3)+\sqrt{65}}{2*7}=\frac{-3+\sqrt{65}}{14}
$
