The Nth term and Algebraic Equations (Factorizing/Expanding)Hey everyone, this is my first post and I decided I need some help with a coming up math exam. Not something as big as a final, but I still need to get good grades. Unfortunately I forgot my math textbook in my locker and its the weekend, so I was wondering if anyone could maybe give me some questions to work on either from some website they use or a textbook. Questions about the Nth term and expanding and factorizing algebraic equations. Not too complex but not too simple either ;) . Thanks tons. Haikus can be weird. Haikus can be confusing.

Re: The Nth term and Algebraic Equations (Factorizing/Expanding)Hi ZainH; In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #3 20101204 05:38:38

Is 3) the only correct one? Or were you just mentioning that because the other two were sort of obvious. Haikus can be weird. Haikus can be confusing. Refrigerator. #9 20101204 05:53:48

Re: The Nth term and Algebraic Equations (Factorizing/Expanding)There are two main ways for your level. Curve fitting and differences. After that there are many,many more.

Re: The Nth term and Algebraic Equations (Factorizing/Expanding)Haven't learnt curve fitting. Differences , I'm assuming is find the difference between the first two terms and that becomes your N then you find what you have to subtract or add to make the equation work? Haikus can be weird.

Re: The Nth term and Algebraic Equations (Factorizing/Expanding)Hi ZainH; If I would have known that you were being taught like that I would not have given you number 1. Have you studied simultaneous equations? Differences are pretty easy too. Want to learn about them? Or want more problems? In mathematics, you don't understand things. You just get used to them.

Re: The Nth term and Algebraic Equations (Factorizing/Expanding)Haven't done simultaneous equations.. and we weren't taught to guess. Our teacher taught us differences. I've got to log off, but if you could post more questions I'd attempt them later and see if I can answer them. If not , I might have to learn about your other methonds. Haikus can be weird.

Re: The Nth term and Algebraic Equations (Factorizing/Expanding)Is just another way to name variables. The n is called a subscript. You can have lots of variables using subscripts. For instance: Using just x we can have any number of variables in this way. Now you can represent a sequence with a rule. would give: When you get to linear algebra and difference equations you will be dealing with many variables, hundreds even thousands. If we just used a to z we could not name them all. Even with small lists subscripts are useful. Supposing you had 26 numbers and named them a to z. If I asked you what the fifteenth number in the list is, you would not know offhand that it was o ( the fifteenth letter ). If you had named them with subscripts you could find the 15th one immediately. It is In mathematics, you don't understand things. You just get used to them.
