Wy multiply elements

-96x^2+72000=0

a = -96; b = 0; c = +72000;
Δ = b2-4ac
Δ = 02-4·(-96)·72000
Δ = 27648000
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:

$\sqrt{\Delta}=\sqrt{27648000}=\sqrt{921600*30}=\sqrt{921600}*\sqrt{30}=960\sqrt{30}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-960\sqrt{30}}{2*-96}=\frac{0-960\sqrt{30}}{-192}
=-\frac{960\sqrt{30}}{-192}
=-\frac{5\sqrt{30}}{-1}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+960\sqrt{30}}{2*-96}=\frac{0+960\sqrt{30}}{-192}
=\frac{960\sqrt{30}}{-192}
=\frac{5\sqrt{30}}{-1}
