Question 613836
the x and y are both positive and squared, with equal coefficients; that means a circle


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


you have to complete the squares for x AND y


x^2 - 3x + ? + y^2 + 8y + ?? = 20


x^2 - 3x + (3/2)^2 + y^2 + 8y + (8/2)^2 = 20 + (3/2)^2 + (8/2)^2


(x - 3/2)^2 + (y + 4)^2 = 38.25
