4x2 + 81y2 - 8x + 324y + 4 = 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: 4x2 - 8x + 81y2 + 324y =   Step 2: 4(x2 - 2x) + 81(y2 + y) =   Step 3: 4(x2 - 2x + ) + 81(y2 + y + ) =   + 4() + 81()   Step 4: 4(x - )2 + 81(y + )2 =   Step 5: (x - )2   (y + )2 +   = 1
