a = 1; b = 0; c = -3721;
Δ = b2-4ac
Δ = 02-4·1·(-3721)
Δ = 14884
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$h_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$h_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{14884}=122$
$h_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-122}{2*1}=\frac{-122}{2}
=-61
$
$h_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+122}{2*1}=\frac{122}{2}
=61
