I'm just wondering if someone can give me a few tips here so that I can understand the basics of when solving a rational equation, why it is ok to remove the denominator by multiplying both sides by the lcd . I find solving equations really difficult. I work part time and thus have no time left to take extra tutoring. Can you guys suggest any online resource that can help me with this subject?

With a bit more specific information about when solving a rational equation, why it is ok to remove the denominator by multiplying both sides by the lcd , I can possibly help you if I knew particulars. If you don’t want to hire a math tutor, who is very costly you can try this program Algebrator which I came across and guarantee to be the best available. This Algebrator is equipped to solve any math problem that you enter and it also clarifies every step of the solution. You only have to represent as your homework. However, it is better to take the help of the Algebrator to learn math rather than use it to copy answers.

I completely agree, Algebrator is great! I am really good in math now, and I have the best grades in the class! It helped me even with the most difficult math problems, like those on graphing lines or complex fractions. I really think you should give it a try .

I remember having problems with inverse matrices, least common measure and multiplying fractions. Algebrator is a really great piece of algebra software. I have used it through several algebra classes - College Algebra, Remedial Algebra and Algebra 2. I would simply type in the problem from a workbook and by clicking on Solve, step by step solution would appear. The program is highly recommended.

Since the Algebrator is easy, any one can get it set up and begin using it within minutes. Prior knowledge is not at all essential to work with the Algebrator . Be it simplifying expressions, quadratic equations or inequalities, go ahead and type it in the search box that comes up as soon as you open Algebrator . This brings you a select set of output that offer all the necessary information on the topic of your choice. You can go through the links one by one and completely get the basic principles of Algebra 2.
