For this kind of problems, You need to remember the formula, (a - c)3 = a3 - 3a2c + 3ac2 - c3 (b + c)3 = b3 + 3b2c + 3bc2 + c3  Now,  (a - c)3 - (b + c)3  = a3 - 3a2c + 3ac2 - .....

Frist remove the coefficient of x 2and y2. We get, x2+y2-4x-6y+1/2=0 Now compare this with, x2+y2+2gx+2fy+c=0 we get , g=-2, f=-3 and c=1/2 Now centr=(h,k)=(-g,-f)=(2,3) and radius=√{g2+f2-c}=.............. Calculate .....
