20s^2-19s+3=0

a = 20; b = -19; c = +3;
Δ = b2-4ac
Δ = -192-4·20·3
Δ = 121
The delta value is higher than zero, so the equation has two solutions

$s_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$s_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{121}=11$


$s_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-19)-11}{2*20}=\frac{8}{40}
=1/5
$


$s_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-19)+11}{2*20}=\frac{30}{40}
=3/4
