Homework Help: Algebra

Posted by TOM on Tuesday, November 11, 2008 at 7:43pm.

I have a question I hope someone can explain it to me.

We are working on Demonstrate that f actoring a polynomial. I was ask Why can you factor x² - 4 but you cannot factor x² + 4? How can you tell quickly which ones you can factor and which you cannot? I am not sure what to answer here. I feel like it has some thing to do with the GCF but I am sure can some just give me an example and explain to me.
