circle ax^(2)+ay^(2)+2gx+2fy+c=0 touches X -axis,if

If the circle x^(2)+y^(2)+2gx+2fy+c=0 touches y -axis then the condition is

Show that the circle S = x^(2) +y^(2) +2gx +2fy +c=0 touches the X - axis if g^(2) =c

Show that the circle S = x^(2) +y^(2) +2gx +2fy +c=0 touches the y - axis if f^(2) =c

If the circle x^(2)+y^(2)+2gx+2fy+c=0 touches x- axis at (x_(1),0) then x^(2)+2gx+c =

Show that the circle S-= x^(2) + y^(2) + 2gx + 2fy + c = 0 touches the (i) X- axis if g^(2) = c

Show that the circle S-= x^(2) + y^(2) + 2gx + 2fy + c = 0 touches the (i) X- axis if g^(2) = c (ii) Y - axis if f^(2) = c.

If the circle x^(2) + y^(2) + 2gx + 2fy + x = 0(c gt 0) touches the y-axis then which one of the following is correct ?
