25x2 + 9y2 - 200x + 36y + 211 = 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 + 9y2 + 36y =   Step 2: 25(x2 - 8x) + 9(y2 + y) =   Step 3: 25(x2 - 8x + ) + 9(y2 + y + ) =   + 25() + 9()   Step 4: 25(x - )2 + 9(y + )2 =   Step 5: (x - )2   (y + )2 +   = 1
