a = -7; b = 19; c = +6;
Δ = b2-4ac
Δ = 192-4·(-7)·6
Δ = 529
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$a_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$a_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{529}=23$


$a_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(19)-23}{2*-7}=\frac{-42}{-14}
=+3
$


$a_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(19)+23}{2*-7}=\frac{4}{-14}
=-2/7
