a = 35; b = -19; c = +2;
Δ = b2-4ac
Δ = -192-4·35·2
Δ = 81
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$p_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$p_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{81}=9$
$p_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-19)-9}{2*35}=\frac{10}{70} =1/7 $
$p_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-19)+9}{2*35}=\frac{28}{70} =2/5 $
