"zeros(x^3-4)" ENTER CAS(1)

In RPN mode, commands have an "argument" specifying how many stack arguments to use. Hence the CAS(1).

Also, remember that when using CAS, global variables like X get replaced with their actual values. Thus, X^3-4 will result in an empty vector (no solution) since you would be equivalently solving for the zeros of a constant function. So do note the lower case x in the commands above.

Thanks Han, I didn't know that.

Hi,

"zeros(x^3-4,x)" [ENTER] CAS [ENTER] would do.
