The denominator factors to . Can you take it from here?

Note that if you multiply the first fraction by , you get ; if you multiply the second fraction by , you get2.) limit as x---->infinity

Do I find a common denominator first, subtract the fractions, and take it from there?

Thus,

Also note that whenever .

Can you take it from here?

Yes, you would use conjugate here. How did you do with this one?3.) limit as x---->2

I think I use the conjugate here.

Well, that is how I tacked the problem. Will post my new answers shortly if I think of a better way to answer them

TIA!

I hope this all made sense to you...
