Δ = b2-4ac
Δ = 53462-4·(-5400)·0
Δ = 28579716
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{28579716}=5346$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(5346)-5346}{2*-5400}=\frac{-10692}{-10800}
=99/100
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(5346)+5346}{2*-5400}=\frac{0}{-10800}
=0
