9x^2-4y^2-18x+8y+41=0
9(x^2 - 2x + .....) - 4(y^2 - 2y + ....) = -41
9(x^2 - 2x + 1) - 4(y^2 - 2y + 1) = -41 + 1 + 1
I will let you finish it from there.
You do realize of course, that your equation does NOT represent an ellipse.
9(x^2 - 2x + .....) - 4(y^2 - 2y + ....) = -41
9(x^2 - 2x + 1) - 4(y^2 - 2y + 1) = -41 + 1 + 1

You forgot to multiply the 9 and the 4 to make the equation = -41 + 9 - 4
