36x2 + 49y2 - 216x + 490y - 215 = 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: 36x2 - 216x + 49y2 + 490y =   Step 2: 36(x2 - 6x) + 49(y2 + y) =   Step 3: 36(x2 - 6x + ) + 49(y2 + y + ) =   + 36() + 49()   Step 4: 36(x - )2 + 49(y + )2 =   Step 5: (x - )2   (y + )2 +   = 1
