possible error section 1

reg1965
Hi Carl
Pre-calculus (version Pi(floor) = 3) section 1 Ex 1.4.2 Q26 part6 f(x) = 2/x for f(a) + f(2). (Page 64)
You give the answer as (a + 2)/2 (page 73)
I cant see how this is achieved....I get (a + 2)/a.
I worked it as 2/a + 2/2 <=> 2(2)/2a + 2(a)/2a <=> 2(a + 2)/2a. Cancel factor of 2 <=> (a + 2)/a
Where have I gone wrong?
Regards
Steve

You are absolutely correct!

Thank you for such a careful reading of our book.  I'll send this off to Jeff so he can include it in the "edit" file.

Thanks again,
Carl
