1.	If ax+by+c=0 is the polar of (1,1) for the circle x2+y2−2x+2y+1=0 and H.C.F. of b,c is equal to 1, then the value of a2+b2+c2 is
Answer» If $a x + b y + c = 0$ is the polar of $(1, 1)$ for the circle $x^{2} + y^{2} - 2 x + 2 y + 1 = 0$ and $H . C . F .$ of $b, c$ is equal to $1$ , then the value of $a^{2} + b^{2} + c^{2}$ is
