I don’t know sorry but try googling the answer
Answer:
we have the centre as:
(−2,0)
radius √12=2√3
Explanation:
The standard equation of a circle is
(x−a)2+(y−b)2=r2
where (a,b)
is the centre, and
r is the radius,
we thus have to complete the square on the given equation.
x2+y2+4x−8=0
rearrange slightly
x2+4+y2−8=0(x2+4+2)+y2−8−22=0(x+2)2+y2−12=0(x+2)2+y2=12
comparing with
(x−a)2+(y−b)2=r2
we have the centre as:
(−2,0)
radius
√12=2√3
