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

Find the parametric representation of circles : (i) x^(2) + y^(2) + 12x - 4y - 1 = 0 (ii) x^(2) + y^(2) + 2gx + 2fy + c = 0 .

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

The equation x^(2) + y^(2) + 2gx + 2fy + c=0 reprsents the circle if

If the radius of the circel x ^(2) + y ^(2) + 2gx+ 2fy +c=0 be r, then it will touch both the axes, if

If the radius of the circel x ^(2) + y ^(2) + 2gx+ 2fy +c=0 be r, then it will touch both the axes, if

If a square is inscribed in the circle x^(2) + y^(2) + 2gx +2fy + c= 0 then the length of each side of the square is
