0=480x-2x2

Solution for 0=480x-2x2 equation:

0=480x-2x^2

We move all terms to the left:

0-(480x-2x^2)=0

We add all the numbers together, and all the variables

-(480x-2x^2)=0

We get rid of parentheses

2x^2-480x=0

a = 2; b = -480; c = 0;
Δ = b2-4ac
Δ = -4802-4·2·0
Δ = 230400
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{230400}=480$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-480)-480}{2*2}=\frac{0}{4}
=0
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-480)+480}{2*2}=\frac{960}{4}
=240
