Question

Can u tell me the answere

Answer 1

Answer:

option a is correct

Step-by-step explanation:

the point of intersection of perpendicular bisectors is

x + y + 1 = 0

x - y + 1 = 0

x = -1

and y = 0

which is centre of the circle

now we know that the equation of circle is

( x - (-1) )² + ( y - 0 )² = 2²

now

x² + 1 + 2x + y² = 4

x² + y² + 2x - 3 = 0 which is the answer
