a = 10; b = 44; c = +42;
Δ = b2-4ac
Δ = 442-4·10·42
Δ = 256
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{256}=16$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(44)-16}{2*10}=\frac{-60}{20} =-3 $
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(44)+16}{2*10}=\frac{-28}{20} =-1+2/5 $
