Let a circle be given by 2x (x − a) + y (2y − b) = 0, (a ≠ 0, b ≠ 0). Find the condition on a & b if two chords, each bisected by the x − axis, can be drawn to the circle from . 
Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION.
(a² > 2b²)
Straight line MN bisected by x-aixs so A (h, 0) is midpoint of MN
So equation of chord of contact MN.
this line passes through (
