**Reiny**, Tuesday, June 15, 2010 at 12:11am9y^2 - 4x^2 + 8x + 18y + 41 = 0

4x^2 - 8x - 9y^2 - 18y - 41 = 0

4(x^2 - 2x + ......) - 9(y^2 + 2y + .... ) = 41

let's "complete these squares"

4(x^2 - 2x + 1) - 9(y^2 + 2y + 1 ) = 41 + 4 - 9

4(x-1)^2 - 9(y+1)^2 = 36

divide by 36

(x-1)^2/9 - (y+1)^2/4 = 1

If you are studying conics you should now be able to identify the conic and state its properties.
