Hello,

I have big problems solving exponential equations in CAS mode with the Solve command.

1 E.g. the equation (x^2-16)*exp(-0,5*x) has x1=4 and x2=-4 as solution. I don't get a solution from Prime.

It works very well (x^2-16)exp(x), it even works with a fraction instead of -0,5, but not with -0,5.

I have tried a lot and have no idea anymore. What am I doing wrong?

best regards

Jürgen
