a = 1; b = -2; c = -7568;
Δ = b2-4ac
Δ = -22-4·1·(-7568)
Δ = 30276
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{30276}=174$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-2)-174}{2*1}=\frac{-172}{2}
=-86
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-2)+174}{2*1}=\frac{176}{2}
=88
