Answer:
The center of the circle is c=50 and radius of the circle is 
Step-by-step explanation:
Given circle equation is

Equation (1) can be written as 
we know that the equation of the circle is of the form

with centre (-g,-f) and radius=
when, g,f and c are constants
Now comparing the (2) and (3) equations we get 2g=-4





and 
Now to find the centre and radius of the given circle equation, substituting the values of g,f,c in the formulae of centre and radius
centre=(-g,-f)
=(-(-2),-7)
centre=(2,7)
Radius=
=
=
=
Radius=
The center of the circle is c=50 and the radius of the circle equation
