Consider a curve `ax^2 + 2hxy + by^2-1=0` and a point P not on the cur – InterviewSolution

1.	Consider a curve `ax^2 + 2hxy + by^2-1=0` and a point P not on the curve.A line is drawn from the point P intersects the curve at the point Q and R.If the product PQ.PR is independent of the sIope of the line, then the curve is:
Answer» The given curve is a circle as it is a property of circle if `QR` is a chord from an outside point `P`, then, `PQPR = PT^2,` where `PT` is the tangent to the circle. So, we can see that `PQPR` is independent of the slope of the line. So, option `(B)` is the correct option.
