Question 617304
the general circle equation is ___ (x - h)^2 + (y - k)^2 = r^2 ___ this is a circle centered at (h,k) with radius r


put the given equation into general form by completing the squares


x^2 + 2x + y^2 + 4y = -4


x^2 + 2x + (2/2)^2 + y^2 + 4y + (4/2)^2 = -4 + (2/2)^2 + (4/2)^2


(x + 1)^2 + (y + 2)^2 = 1
