502+1202=c2

Solution for 502+1202=c2 equation:

502+1202=c2

We move all terms to the left:

502+1202-(c2)=0

We add all the numbers together, and all the variables

-1c^2+1704=0

a = -1; b = 0; c = +1704;
Δ = b2-4ac
Δ = 02-4·(-1)·1704
Δ = 6816
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$c_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$c_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

The end solution:

$\sqrt{\Delta}=\sqrt{6816}=\sqrt{16*426}=\sqrt{16}*\sqrt{426}=4\sqrt{426}$
$c_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-4\sqrt{426}}{2*-1}=\frac{0-4\sqrt{426}}{-2}
=-\frac{4\sqrt{426}}{-2}
=-\frac{2\sqrt{426}}{-1}
$
$c_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+4\sqrt{426}}{2*-1}=\frac{0+4\sqrt{426}}{-2}
=\frac{4\sqrt{426}}{-2}
=\frac{2\sqrt{426}}{-1}
