It's hard for me... I did fine in all my other maths, but it's getting hard. I need to do decent on this qui to pass the class basically, but I don't think it will be too bad....

Humm....you don't need to use Quotient Rule on that. You can re-write it as -(x^(-2)) and use Power Rule. Much simpler. You get: 2(x^(-3)) -> 2/(x^3)

edit: Quotient rule would work though.
