So i only know a little bit of factoring. it doesn't help that my math teacher is an idiot and just rambles on about football (he is the varsity coach) all hour.

so can someone explain to me how to factor the sum or the difference of to cubes. I dont just want an answer to the problems i want to understand how to do it.

i cant make the little threes for the cubed signs on the computer but here are some example problames.

A piece of wire 13 m long is cut into two pieces. One piece is bent into a square and the other is bent into an equilateral triangle. (Give your answers correct to two decimal places.)

(a) How much wire should be used for the square in order to maximize the total area?

(b) How much wire should be used for the square in order to minimize the total area? 5.65 m

I found B(and it is correct), I just cant find A for some odd reason, if you could show the steps and the answer that would be highly appreciated.
