This'll be my last one. Not to be greedy, but can you give me the medals for the ones I finished?

Answer 4

Starting with form \[\frac{7}{n-3}+\frac{n}{n+3}\]
Do conjugates again.
\[\frac{7}{n-3}(\frac{n+3}{n+3})+\frac{n}{n+3}(\frac{n-3}{n-3})\]
Simplify.
\[\frac{7n+3}{n^2-3}+\frac{n^2-3n}{n^2-3}=\frac{n^2+4n+3}{n^2-3}\]
There's a (n+3) in there that cancels to give you
\[\frac{n+3}{n-3}\]
All done!
