How would the fraction  be rewritten if its denominator is rationalized using difference of squares?

Jun 3rd, 2015

If the denominator is of the form x^2 -a^2 , then it can be factorized as (x-a) (x+a)

Eg: x^2 - 25 = (x+5) (x-5)

Please let me know if you have any questions and best me if you are satisfactory.
