text: On the contrary, given the general quadratic equation, if C is positive, the equation represent a circle having the center (p, q) and radius expressed in terms of a square root.
text: If P = (x 1 , y 1 ) and the circle has centre (a, b) and radius r, then the tangent line is perpendicular to the line from (a, b) to (x 1 , y 1 ), so it has the form (x 1 − a)x
