Status: Waiting for your answers. 81x^{2} + 9y^{2} - 486x + 36y + 36 = 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 1:81x^{2} - 486x + 9y^{2} + 36y = Step 2: 81(x^{2} - 6x) + 9(y^{2} + y) = Step 3: 81(x^{2} - 6x + ) + 9(y^{2} + y + ) = + 81()+ 9() Step 4: 81(x - )^{2} + 9(y + )^{2} = Step 5: (x - )^{2} (y + )^{2} + = 1
