Question

The product of the prosperolientas
distance from the point (-2,3) to
the unes x²-y² +2x+1=0 is​

Answer 1

Answer:

+1=0

(x−2)

2

−1+(y+2)

2

−4+1=0

(x−1)

2

+(y+2)

=4

Comparing above equation with the standard equation of circle (x−h)

2

+(y−k)

2

=r

, we get

h=1,k=−2

∴ Centre of circle (1,−2)
