Integration issue

[Caboz]

Hello

I've got a HP50g and tried to integrate by using RISCH the next expression

A*exp(-Ax)*x^2

but the calculator only integrates x^2 and take the rest like a constant.

using wolfram should be https://www.wolframalpha.com/input/?i=%E...)+x%5E2+dx

any ideas? tried all cas menu's modifications and flags, rpn and algebraic mode

Thanks

Hello, you are missing the * sign between the A and the x.

Thank you so much, it worked and checking rigorous and non-rational in cas modes
