a = 2; b = 0; c = -88200;
Δ = b2-4ac
Δ = 02-4·2·(-88200)
Δ = 705600
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{705600}=840$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-840}{2*2}=\frac{-840}{4}
=-210
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+840}{2*2}=\frac{840}{4}
=210
