Answer:
The center of the circle is
Step-by-step explanation:
Let the equation of the circle be
, where (-a,-b) is the center of this circle.
The points lying the circle must satisfy the equation of this circle.
A(0,0)
We substitute this point to get;
B(-3,0)
But c=0
C(1,2)
Put the value of 'a' and 'c' to find 'b'
b=-2
Hence the center of the circle is
