Maple Grouping Terms with Maple: Simplify Expressions with e | Step-by-Step Guide

[vlad2006]

I have an expression like this:
expr1:=x*e^2+y*e+(x^2-1)*e^2
How i can, using maple, group terms with e.
In this case with result like:
expr2:=e^2*(x+x^2-1)+e*y

 

[benorin]

use the command:

collect(x*e^2+y*e+(x^2-1)*e^2,e);

which has the result:

(x+x^2-1)*e^2+y*e
