Partial fraction decomposition
Hi
I searched and did not find topic I was looking for in my search result . I decided to ask,
I have a simple partial fraction and would like to decompose the rational integral fraction, using HP prime.
I had no luck achieving said result which is expected of the HP prime.. I'm familiar with the HP 55 G and 50.
Example
x /(x^2-4)
Any help how to go about working above problem on the HP prime will be helpful

RE: Partial fraction decomposition
Toolbox->Cas->Algebra->Partial Fraction is the UI to get there.

Note you could also have gone into Toolbox->Catalog-> and gone down to "P" and i suspect it would have jumped out at you. Another way would be to press the HELP button, tap the Search key and search through the on-calc help for "partial" or similar.

Although I work for the HP calculator group, the views and opinions I post here are my own.

Seems like you have values stored into the variable x in the CAS. Delete this variable: purge(x). If you are still not seeing the right answer, it may be that you have other instances of the variable x sitting around (check the memory browser).
