Hey guys, I need some help. I am stuck on this one :(

A circle lies in the third quadrant and touches both coordinate axes. If the length of the tangent from the point A(-4, 2) to the circle is 5, determine the equation of the circle.

the circle formula is (x–h)2 + (y – k)2 = r2
so
(x – (–4))^2+ (y – 2)^2=(5)^2
therfore (x+4)^2+(y–2)^2=25
