# x2+y2-3x+1=0 x2+y2-x+5=0 x2+y2-8x+6y=8 x2+y2-4x+8y=7

General equation of circle ,

Now find the points of intersection of the two circles.

At the intersection,

Putting the value of x1 in the equation of any of the two circle to find y1.

Now we have 3 points through which the circle is passing,     ,       ,

Now putting these points in general equation we will have 3 equations.

.............(1)

...............(2)

..............(3)

Putting values and after solving these 3 equations we will get,  ,       ,

Putting these values in the general equation we will get the equation of circle,

Option (1) is correct
