a = 1; b = -480; c = +1;
Δ = b2-4ac
Δ = -4802-4·1·1
Δ = 230396
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

The end solution:

$\sqrt{\Delta}=\sqrt{230396}=\sqrt{4*57599}=\sqrt{4}*\sqrt{57599}=2\sqrt{57599}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-480)-2\sqrt{57599}}{2*1}=\frac{480-2\sqrt{57599}}{2}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-480)+2\sqrt{57599}}{2*1}=\frac{480+2\sqrt{57599}}{2}
