48000x-4x^2=0

Solution for 48000x-4x^2=0 equation:

48000x-4x^2=0

a = -4; b = 48000; c = 0;
Δ = b2-4ac
Δ = 480002-4·(-4)·0
Δ = 2304000000
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{2304000000}=48000$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(48000)-48000}{2*-4}=\frac{-96000}{-8}
=+12000
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(48000)+48000}{2*-4}=\frac{0}{-8}
=0
