Help with adding rational expressions with unlike denominators

Hi! I'm new here! My name is Christina and I am currently in Algebra 2 in ninth grade.

The problem that I need help with is 2-a^2/a^2+a plus 3a+4/3a+3

I got 6+4a/3a(a+1) but I'm not sure if it's right.

Thanks!

Re: Help with adding rational expressions with unlike denominators

You result is correct. Good work!(Cool)

Two things that will help you get better help:

1.) Post in the appropriate area. This forum is for things like abstract algebra, Galois theory, groups, rings, homomorphisms, etc. While I can certainly appreciate that any math may feel advanced while it is being learned, this isn't what is meant by advanced algebra here. I also see folks posting problems they feel are "complex" in the complex analysis forums. It is a common mistake, and I only tell you this as a means for you to get better help.

2.) Use bracketing symbols to clearly indicate the problem. For example, it would be more clear had you typed:

(2 - a^2)/(a^2 + a) + (3a + 4)/(3a + 3)

and for really nice formatting, look into using $\displaystyle \LaTeX$ and you can display it as:

$\displaystyle \frac{2-a^2}{a^2+a}+\frac{3a+4}{3a+3}$

Thanks so much!! Yep, it will take a while to get used to this site. I will definitely look into using that! Thanks for your help!
