MC III Algebra Help

Hi I’m doing the hw and I need help on 2.29, 2.33, and 2.34. I tried using the binomial theorem for 2.33 and 2.34, but I couldn’t find a combination which resulted in the series shown. For 2.29 I’m just stuck. Thanks for the help!

Re: MC III Algebra Help

Please refer to my hints for another students on this chapter.  For 2.29, after expanding everything and clearing the denominators, try to write the result as a geometric series (some terms are missing, but you can add them in and subtract them), and eventually you get a polynomial that is shorter and easier to handle.

I added some more details for the answer to Aiden Gao and Kevin Song's questions.  Those should answer some of your questions as well.
