Problem with zeros and solve in HP Prime.

I changed the expression to string and use zeros("expression", "v"), v="x". I should be getting 3 zeros [1,2,-1] which I get in CAS and in HOME but when running program to find the zeros of the same expression I am getting all kind of numbers around twenty which are obviously not zeros I should get. I have no idea how to fix the problem.
Thanks.

Use the following form in your program:

CAS("zeros((x-1)*(x-2)*(x+1)*e^(-1/2*x^2),x)");

It works fine.
