Δ = b2-4ac
Δ = 46172-4·(-5184)·0
Δ = 21316689
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{21316689}=4617$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(4617)-4617}{2*-5184}=\frac{-9234}{-10368}
=57/64
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(4617)+4617}{2*-5184}=\frac{0}{-10368}
=0
