Answer»

If $(x_{1}, y_{1})$ is a point inside the circle $x^{2} + y^{2} + 2 g x + 2 f y + c = 0$ Given two expressions $S_{1}$ and $T_{1}$ such that,

$S_{1} = x_{1}^{2} + {y_{1}}^{2} + 2 g x_{1} + 2 f y_{1} + c$

$T_{1} = x x_{1} + y y_{1} + g (x + x_{1}) + f (y + y_{1}) + c$

Then the equation of chord centered at $(x_{1}, y_{1})$ is
