    49x2 + 16y2 - 196x + 160y - 188 = 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 1:49x2 - 196x + 16y2 + 160y =  
Step 2: 49(x2 - 4x) + 16(y2 + y) =  
Step 3: 49(x2 - 4x + ) + 16(y2 + y + ) =  
+ 49()
+ 16()
 
Step 4: 49(x - )2 + 16(y + )2 =  
Step 5:
(x - )2  (y + )2
+
 
=
