    25x2 + 81y2 - 200x + 486y - 896 = 0 is the general form of an ellipse. Write the equation of this conic section in standard form by filling in the appropriate values for each open response.

Step 1:25x2 - 200x + 81y2 + 486y =  
Step 2: 25(x2 - 8x) + 81(y2 + y) =  
Step 3: 25(x2 - 8x + ) + 81(y2 + y + ) =  
+ 25()
+ 81()
 
Step 4: 25(x - )2 + 81(y + )2 =  
Step 5:
(x - )2  (y + )2
+
