Well the book I'm learning from suggests you take the following:

y = ( (2x + 3) / (x + 4) ) ^ 2

And use the chain rule first.

However, the way I find easiest is to re-arrange it so that:

y = (2x + 3) ^ 2 / (x + 4) ^ 2

That way I can go straight to the quotient rule although it is a little bit more cluttered (just more inside the brackets).

Is my way acceptable?

I am doing the same thing for sqrt( (3 - x) / (3 + x) )

Instead of doing it the way my book suggests I re-arrange it to:

sqrt(3 - x) / sqrt(3 + x)

And then once again I rearrange it to:

(3 - x) ^ 1/2 / (3 + x) ^ 1/2
