Let x2 + y2 - 2x - 2y = 0 & x2 + y2 + 2ax + 2ay + b = 0 are two different circles. If L is the only common tangent of these circles such that their centers are mirror images in L, then which can be true -

Accepted Answer

Possible when two circles touch each other & having same radiir1 = r2 &#8658; &#8730;2 = c1c2 = r1 + r2&#8658; &#8658; a = - 3 & b = 16Line L is x + y = 4
