a = 2; b = 0; c = -82.6;
Δ = b2-4ac
Δ = 02-4·2·(-82.6)
Δ = 660.8
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{-(0)-\sqrt{660.8}}{2*2}=\frac{0-\sqrt{660.8}}{4}
=-\frac{\sqrt{}}{4}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+\sqrt{660.8}}{2*2}=\frac{0+\sqrt{660.8}}{4}
=\frac{\sqrt{}}{4}
