\(\displaystyle \lim _{n \to \infty} \frac{3n-\sqrt{4n^2+n}}{3n+\sqrt{4n^2-n}}\)

\(\displaystyle \lim _{n \to \infty} \frac{\sqrt{9n^2-n}-2n}{\sqrt{9n^2-n}+2n}\)

Those kind of problems will be on my exam,which is very close,and i dont get it how to deal with this limits.....

I just say thank you for your help!
