#1**+1 **

Hint:

General form of circle's equation is,

(x-h)^2+(y-k)^2=r^2

another hint

collect the x's in 1 barract and the y's in another barract added to it and move any number to the other side

then complete the square for both x and y and don't forget to add the same amount to the other side.
