You can put this solution on YOUR website! Put this equation into standard form and solve the conic:
x^2+9y^2-4x+54y+4=0
---
x^2-4x+4 +9(y^2+6y+9) = -4+4+9*9
---
(x-2)^2 + 9(y+3)^2 = 81
---
Standard for;
[(x-2)^2/81] + [(y+3)^2/9] = 1
-------------------------------------
Ellipse with center at (2,-3)
etc.
