.

Then the center is at the point  (-sqrt%282%29,-sqrt%282%29)  and the radius is  sqrt%282%29.


Therefore, the standard form equation of this circle is


    %28x%2Bsqrt%282%29%29%5E2 + %28y%2Bsqrt%282%29%29%5E2 = 2.

if a circle is tangent to both axes, is in the third quadrant, and has a radius of sqrt%282%29, the center will be at (-sqrt%282%29, sqrt%282%29)
the center-radius form of its equation is:
%28x-%28-sqrt%282%29%29%29%5E2%2B%28y-sqrt%282%29%29%5E2=%28sqrt%282%29%29%5E2
%28x%2Bsqrt%282%29%29%5E2%2B%28y-+sqrt%282%29%29%5E2=2

There are a few people on here who need to STAY away from this forum, as day after day after day after day, they do nothing but confuse the H..L 
out of these people who ask for help!
This one who responded is certainly one of them, by far!
Does this person REALLY NOT know where the 3rd Quadrant is? My LORD!!
