Consider the family of circles x^(2)+y^(2)-2x-2ay-8=0 passing through two fixed points A and B . Also, S=0 is a cricle of this family, the tangent to which at A and B intersect on the line x+2y+5=0 . The distance between the points A and B , is

Circle x^(2)+y^(2)-2x-lambda x-1=0 passes through to fixed points,coordinates of the points are

Consider a family of circles passing through two fixed points A(3,7)&B(6,5) then the chords in which the circle x^(2)+y^(2)-4x-6y-3=0 cuts the members of the family are concurrent at a point.Find the coordinates of this point.

consider a family of circles passing through two fixed points S(3,7) and B(6,5) . If the common chords of the circle x^(2)+y^(2)-4x-6y-3=0 and the members of the family of circles pass through a fixed point (a,b), then
