I've always wanted to learn when simplifying a rational expression, why do you need to factor the numerator and the denominator, it seems like there's a lot that can be done with it that I can't do otherwise. I've searched the internet for some good learning tools , and consulted the local library for some books, but all the information seems to be directed to people who already understand the subject. Is there any tool that can help new people as well?

Although I understand what your situation is , but if you could elaborate a bit on the areas in which you are facing struggling, then I might be in a better position to help you out . Anyhow I have some advice for you, try Algebrator. It can solve a wide range of questions, and it can do so within minutes. And there’s more to come, it also gives a detailed step-by-step description of how it arrived at a particular solution . That way you don’t just find a solution to your problem but also get to understand how to go about solving it. I found this software to be particularly useful for solving questions on when simplifying a rational expression, why do you need to factor the numerator and the denominator. But that’s just my experience, I’m sure it’ll be good no matter what the topic is .

Hello friends I agree, Algebrator is the greatest. I used it in Intermediate algebra, Intermediate algebra and Basic Math. It helped me figure out the hardest algebra problems. I'm thankful to it.

I remember having often faced difficulties with hyperbolas, exponential equations and syntehtic division. A truly great piece of math program is Algebrator software. By simply typing in a problem from workbook a step by step solution would appear by a click on Solve. I have used it through many algebra classes – Algebra 1, Intermediate algebra and Intermediate algebra. I greatly recommend the program.
