Assertion : Let S1 : x2 + y2 – 10x – 12y – 39 = 0
S2 : x2 + y2 – 2x – 4y + 1 = 0
S3 : 2x2 + 2y2 – 20x – 24y + 78 = 0
The radical centre of these circles taken pairwise is
(–2, –3)
Reason : Point of intersection of three radical axis of three circles taken in pairs is known as radical centre
S2 : x2 + y2 – 2x – 4y + 1 = 0
