symbolic results in CAS
In CAS I can invoke Toolbox > Algebra > Factor as follows:
factor(x^4  1) > (x1)*(x+1)*(x^2+1) So far so good. Now, if I store 2 into variable "x" and invoke factor again we have factor(x^4  1) > 15 In other words, if I have used a variable I can no longer obtain symbolic results with that variable. How do I mark a variable unused so it can be used for symbolic calculations?
