So, I'm evaluating a limit that has a few surds in it.
I believe i've reached a crucial point where I need to cancel like terms, I just want to be sure I'm doing it all correctly:
(a - 9 - 27 ) / (a - 3 - 9)
I cancelled the a's and the 's and simplified the coefficents
My limit value in the question limit ---> 9
and when i sub this into + 6 my answer = 9
is this right? :/
limits- I've so lost mine :/ Watch

Can you write out the question please, as in the book.
