[HP Prime] expand(collect(...)) Is there any better way?

HP Recommended

I've been summing 3rd grade polynomials and the resulting expressions been growing and growing...

 

I expected to have for answer a simple 3rd grad polynomial as well, but I couldn't have it.

 

The solution I found has been doing "expand(collect( cp0 ))", where cp0 is the sum polynomial itself. Then I've got what I wanted.

 

Would there be any better (or "cleanner") way to have it? Would it be possible to configure CAS to answer this way directly?

Thank you.
