Δ = b2-4ac
Δ = 57602-4·(-240)·0
Δ = 33177600
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{33177600}=5760$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(5760)-5760}{2*-240}=\frac{-11520}{-480}
=+24
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(5760)+5760}{2*-240}=\frac{0}{-480}
=0
