81x2 + 36y2 - 648x + 288y - 1044 = 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: 81x2 - 648x + 36y2 + 288y =   Step 2: 81(x2 - 8x) + 36(y2 + y) =   Step 3: 81(x2 - 8x + ) + 36(y2 + y + ) =   + 81() + 36()   Step 4: 81(x - )2 + 36(y + )2 =   Step 5: (x - )2   (y + )2 +   = 1
