377.72^2+252.96^2=c^2

Solution for 377.72^2+252.96^2=c^2 equation:

377.72^2+252.96^2=c^2

We move all terms to the left:

377.72^2+252.96^2-(c^2)=0

We add all the numbers together, and all the variables

-1c^2+206661.16=0

a = -1; b = 0; c = +206661.16;
Δ = b2-4ac
Δ = 02-4·(-1)·206661.16
Δ = 826644.64
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$c_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$c_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$c_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-\sqrt{826644.64}}{2*-1}=\frac{0-\sqrt{826644.64}}{-2}
=-\frac{\sqrt{}}{-2}
$
$c_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+\sqrt{826644.64}}{2*-1}=\frac{0+\sqrt{826644.64}}{-2}
=\frac{\sqrt{}}{-2}
