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

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

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 ?

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

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

If x-axis is tangent to the circle x^(2) +y^(2) +2gx + fy + k = 0 . Then which one of the following is correct ?

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

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