Does anybody no how to do this and could give me an exaple I no its going to be in my test and I need help fast ?

Do what? If you mean factoring, you're painting with a broad brush. Please post a specific problem and I or someone else will be glad to lend a hand.

Also, in your context, it's 'know'... not 'no'. Maybe brush up on grammar as well.

Well, if you're that desperate post a problem.
