RE: HP Prime CAS programming
Have you tried:

CMD1:="diff(3*x^2+5*x,x,1)"

or

CAS.diff("3*x^2+5*x,x,1")

Both return 6*x+5

for me.

Good point. In fact I left on purpose the example with the two "different" results, so it is possible to quickly imagine alternatives like yours or, e.g., if you implement a custom CAS function to be called this way, add an extra simplify() command if needed.
