(e^2+1+2e/4) *   e^-1  

 

This needs some more parentheses to clarify exactly what is wanted.  

 

The problem I'm having specifically is the 2e/4 term.  

Why wouldn't that have just been called e/2 instead.  

 

The only reason I can think of for writing 2e/4 instead of simply e/2   

is that the denominator 4 applies to everything that comes before.  

 

Thusly                                         e2 + 1 + 2e         e–1  

                                                  —–————  •  ———  

                                                           4                  1  

 

That can be written as                 (e + 1)2   

                                                   –––––––  

                                                        4e  

 

I don't know if this is correct ... "correct" meaning what was  

actually wanted, so I'm not going to paint it red like I usually do.
