Question

The image below is just an example of how the questions I'm giving you work. 

Question: Simplify the following after expanding.

Note: The questions that contain a slash mean an upon, such as '1/3' means 1 upon 3. 

[1] 
1/4 (x2y2 - 2) - (xy + 1/2)2.
[2] (x + 1/x)+ (x - 1/x)- 2.

Please do not make them very complicated, instead, make them easy to understand so that I can understand them myself as well. Thank you very much.
