X2+(x-2)2=244

Solution for X2+(x-2)2=244 equation:

X2+(X-2)2=244

We move all terms to the left:

X2+(X-2)2-(244)=0

We add all the numbers together, and all the variables

X^2+(X-2)2-244=0

We multiply parentheses

X^2+2X-4-244=0

We add all the numbers together, and all the variables

X^2+2X-248=0

a = 1; b = 2; c = -248;
Δ = b2-4ac
Δ = 22-4·1·(-248)
Δ = 996
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:

$\sqrt{\Delta}=\sqrt{996}=\sqrt{4*249}=\sqrt{4}*\sqrt{249}=2\sqrt{249}$
$X_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(2)-2\sqrt{249}}{2*1}=\frac{-2-2\sqrt{249}}{2}
$
$X_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(2)+2\sqrt{249}}{2*1}=\frac{-2+2\sqrt{249}}{2}
