1. ## Polynomials

I have no idea what polynomials are and what they are used for... If someone could help me it would be apreciated...

2. The wikipedia page on polynomials is quite good. It gets a bit advanced towards the end, but you'll have plenty to go on before you get that far down the page.

Maybe have a go at reading some of it, and then if you get stuck on any part, or have any more specific questions, you could ask here?
