I am having problem with representing a 2 degree eq in the form of a ellipse

$\displaystyle 2x^2 + 3y^2 - 4x - 12y +13 = 0$

please provide me with the starting few steps or clues on how to solve this .I have already done the tranformation procedure and the result is this equation .I am stuck at this step as i dont know what to do next ?
