Step-by-step explanation:

Hello,

We need to work a little bit of the expression to see if we can simplify.

Do you remember this formula?

   for any a and b reals, we can write

We will apply it.

For any x real number different from 3 (as dividing by 0 is not allowed)

So the winner is C !!

Hope this helps.

Do not hesitate if you need further explanation.

Thank you
