The two circles x2+y2−2x−3=0 and x2+y2−46y−8=0 are such that
They touch each other
They intersect each other
One lies inside the other
Each lies outside the other.
The two circles are x2+y2−2x−3=0 and x2+y2−4x−6y−8=0 . C'(2,3) respectively and their radii are 2 and 21 respectively, Here,
|CC'|=(2−1)2+(3−0)2=10
Since |2−21|<|CC'|<2+21 .
Therefore, the two circles interest in two distinct points
