I think I can cancel the 5 and 25 (No! No! A thousand times NO!) and the 12 and 6 (Yes)

(Your incorrect result)

Here's what you need to do:

. Factoring a 6 out of the numerator of the second fraction and the denominator of the first was the right thing to do.

. Now, recognize the numerator of the first fraction as the difference of 2 squares, , so your expression becomes:

. Now recognize that . Your expression becomes:

. NOW you can take the common factor of from the numerator and denominator

Done.
