Question 577653
Write an equation in general form of a circle with the given properties

Center at (-2,7); r=8 sqrt (5)
------------------
{{{(x+2)^2 + (y-7)^2 = 64*5}}}
{{{x^2 + 4x + 4 + y^2 - 14y + 49 = 320}}}
{{{x^2 + 4x + y^2 - 14y - 267 = 0}}}
-----------------------
Looks right to me.
-------------------------
my answer was x^2 + y^2 + 4x - 14y - 267 = 0  marked incorrect

i tried a different equation and got it right. I dont know where I am making a mistake.  Here is the one I tried and got correct but will not get credit for.

(-9,3); r=4 sqrt (2)

answer  x^2 + y^2 +18x - 6y + 58 = 0
