Mathematica gave me an output of this form where expr in each
parentheses is long winded expression......

A + p^2 (expr 2) + p (expr 1) + p^3 (expr 3)...

I got this output by using Collect[ expr,p]....

but I want the output in this form for the obvious reason....

A + p (expr 1 )  + p^2 (expr 2) +   p^3 (expr 3)...

How do I get that?

I notice if I type in    p^2 (a+b) + p (b+c) + p^3 (a+b+c)   the output
form is, in fact,  

  (b+c) p + b(a+b) p^2 + (a+b+c)  p^3.......

why the difference?


thanks....jerry blimbaum
