This Question needs to get a Gold medal for being very Hard and Tricky!

Bunuel 's Explanation:

Quote:
In the denominator we have x - y, which can be written as x−y=(x√)2−(y√)2=(x√−y√)(x√+y√)

NEEDS to get a Double Medal.

Here is where i went wrong. i didn't understand how you rephrased the question stem, in particular the denominator, how you went from X-Y to the syplified form in the above.

I have never seen or known that X-Y can be simplified in the manner you did to rephrase this question.

Supurb explanation!

Thanks!
