If theline y=x touches the circle `x^(2)+y^(2)+2gx+2fy+c=0` at P where `OP=6sqrt2` then c=

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 origin lies inside the circle x^(2) + y^(2) + 2gx + 2fy + c = 0 , then

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

If y-axis touches the cirle. x^(2) + y^(2) + gx + fy +c/4 = 0 then the normal at this point intersects the circle at the point.

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