25x2 + 64y2 - 100x + 512y - 476 = 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 - 100x + 64y2 + 512y =   Step 2: 25(x2 - 4x) + 64(y2 + y) =   Step 3: 25(x2 - 4x + ) + 64(y2 + y + ) =   + 25() + 64()   Step 4: 25(x - )2 + 64(y + )2 =   Step 5: (x - )2   (y + )2 +   = 1
