<em>x</em> ² + 2<em>x</em> - 2<em>xy</em> - 2<em>y</em> + <em>y</em> ² = (<em>x</em> ² - 2<em>xy</em> + <em>y</em> ²) + 2 (<em>x</em> - <em>y</em>)
… = (<em>x</em> - <em>y</em>)² + 2 (<em>x</em> - <em>y</em>)

-I usually close all my electronics except my computer, so that I can use it for research purposes
-Drink a glass of fresh cold water

- De stress
-Get things out of the way, like if you have to do chores, do those first so you dont have anything to worry about
-Get a good pen. This is sososo important to me. If i write good, I can understand what i'm writing and its just really really recommended to get a good pen/pencil (:
-Take breaks. Every 30 minutes studying, you get a 5-7 minute study break.
-Study at the same time everyday. Your mind will get used to it and will actually be enjoyable in the future!
