Re: Multiplying and Dividing Rational Expressions
There is a mistake on the first one so if B =1 then that is the answer for 12.

Re: Multiplying and Dividing Rational Expressions
Hold it just got back on. I got cut off.
There is a mistake on 15 on the 2 step.
But I do not think it can be simplified either.

Re: Multiplying and Dividing Rational Expressions
Hi zee-f;
Yes, I said that. There is a mistake on step 2. So maybe you should put that as the answer.
