Δ = b2-4ac
Δ = 02-4·(-4)·435600
Δ = 6969600
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{6969600}=2640$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-2640}{2*-4}=\frac{-2640}{-8}
=+330
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+2640}{2*-4}=\frac{2640}{-8}
=-330
