Δ = 13465
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(115)-\sqrt{13465}}{2*-10}=\frac{-115-\sqrt{13465}}{-20}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(115)+\sqrt{13465}}{2*-10}=\frac{-115+\sqrt{13465}}{-20}
