You're nearly there; you're correct up until the third from the last line, where you've dropped a plus sign in the denominator. You then simply need to multiply the top and bottom by x^2 y^2.
Remember, when multiplying out a fraction on both the top and bottom, it involves multiplying every term.
The fraction 2y+2/x^2 / -2x+3/y^2 is correct (though you can write the bottom as 3/y^2- 2x)
The working out beyond that is wrong. First, try multiplying EVERY term by x^2 to get rid off the fraction in the numerator, and do the same for the y^2 in the denominator.

You only multiplied the terms in the numerator by x^2. Multiply EVERY term. Take it slow and you'll get it. Multiply the 2y, -2x and 3/y^2 by x^2. Then do the same for the y^2.
