A circle intersects at point $A(x_1, 0)$ and $B(x_2,0)$ at $x$-axis. If the equation the circle is $x^2+y^2+2gx+2fy+c = 0$. Then what is the length of $AB$?

2Why not just $|x_1-x_2|$? – Peter Foreman Jul 19 '19 at 14:57

Do you mean the length of the arc $AB$? What have you tried? – Robert Z Jul 19 '19 at 14:58

No, Sir.The length of segmented part of X axis. – Ghost Jul 19 '19 at 15:03

Are you meant to express this length in terms of $f$, $g$ and $c$? – amd Jul 20 '19 at 00:09

Absolutely Sir. Sorry for the delay. – Ghost Jul 20 '19 at 09:02
