Could you explain where you are running into problems and maybe I can help you get past them. I don't think you learn much if I just do the problem for you.

How can i simplify the denominator ?

- Apr 2nd 2012, 12:58 PMMathVideosRe: simplify
Hint: recall the difference of 2 squares.

$\displaystyle a^2-b^2=(a+b)(a-b)$

Think of the denominator as (a-b)

Think you can take it from here? Think about it for a minute or two and if you still can't get it, let me know. - Apr 2nd 2012, 06:22 PMWilmerRe: simplify
