 Posted: Friday 29th of Dec 09:06 I have a couple of problems based on when solving a rational equation why is it ok to remove the denominator by multiplying both sides by the lcd I have tried a lot to solve them myself but in vain. Our professor has asked us to solve them out ourselves and then explain them to the entire class. I fear that I will be chosen to do so. Please help me!

 Posted: Sunday 31st of Dec 09:12 Algebrator truly is a masterpiece for us algebra students. As my dear friend said in the preceding post, not only does it solve questions but it also explains all the intermediary steps involved in reaching that final solution . That way you don’t just get to know the final answer but also learn how to go about solving questions right from the first step till the last, and it helps a lot in working on assignments.
