Really struggling with a couple of these.

x² - y² /y
________
x - y/y³


and


2x + 4/x
_______
1/3x² + 1/6
@ D R - I have the answers and those aren't even remotely close.

Answers alone do me know good. I need to know how to solve them.
The answers are y²(x+y) and 12X. I need to know to get it tho'. I thought I knew exactly how to do these but I'm getting the wrong answers.
