Wy multiply elements

-250000x^2+125x+5400=0

a = -250000; b = 125; c = +5400;
Δ = b2-4ac
Δ = 1252-4·(-250000)·5400
Δ = 5400015625
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:

$\sqrt{\Delta}=\sqrt{5400015625}=\sqrt{15625*345601}=\sqrt{15625}*\sqrt{345601}=125\sqrt{345601}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(125)-125\sqrt{345601}}{2*-250000}=\frac{-125-125\sqrt{345601}}{-500000}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(125)+125\sqrt{345601}}{2*-250000}=\frac{-125+125\sqrt{345601}}{-500000}
