Rewrite: $\frac{\sqrt{x}\, -\, \sqrt{a}}{x\, -\, a}$

This was on a test and I didn't know the answer, please help. I thought it was 0 but I was wrong.

What were the instructions? What were you supposed to do with this expression? How did you arrive at your solution value of "0"?

Please be complete. Thank you! :wink:
