Step-by-step explanation:
Given ;
re - arranging , we have
comparing with the general equation
This means that
also
The coordinate of the center is (-g,-f)
Therefore;
the coordinate of the center = (4,-3)
the formula for calculating r is given by:
METHOD 2
using completing the square method , we have
completing the square , we have
comparing with the general equation
where a and b are the coordinate of the center , that is
the coordinate of the center is ( 4 , -3)
