There's a function that's part of CAS and you're complaining that it's unavailable when CAS is unavailable, right?

That's like walking into a fishmonger's and complaining to him that you can't buy swordfish because your local government has forbidden the sale of that fish. There's no point in complaining to the fishmonger, he's only doing what he's told to do. It's your local government that you want to petition so that they allow the sale of swordfish.

Similarly here, it's not HP that you want to petition, it's your education authority.

I am sorry and I clearly get your point. Let me re-state my question:

1) (In CAS off mode) What is the fastest way to find the roots of a polynomial including imaginary roots. A lot of calculators out there that does not have CAS but still can solve for roots.

2) Why does POLYROOT() is uppercase but it is part of CAS. Aren't only the lowercase functions are CAS?

I do complained a bit. But, mainly, I am asking for solutions to my problem. Which is the two problems. I do agree that "it's not HP that you want to petition, it's your education authority". But, finding a solution for this calculator would be much easier than fixing the education. If only there's a solution for the calculator. If there is no way I can solve that without turning on CAS, I will just accept it and maybe if required change to another calculator. It would be really sad though cuz this calculator is really good in other aspects like interface and performance. Sorry for the bad English. Hope you get my point.
