Please use the same name for all of your posts.
By using different names, you're usurping names that are already used by other students.

Rewrite the equation in the form
(x + 2)^2 + (y  3)^3 = 11
This shows that it is a circle centered at x = 2, y = 3.
See of you can guess the radius, from the constant term on the right.
