Hello,

I am currently trying to solve a symbolic equation for a variable and the solution I am receiving has roots of ‘z’ which was not previously defined or used in any of my equations. Here is where/how it appears:

In another case I modified the simplifcation process to attempt get a usable solution and ended up with just the variable ‘u’ which was not previously used or defined either. Is there a known reason why these variables are appearing. I’ve read that equations of the fifth degree can be hard to solve symbolically, which may be the reason for the ‘z’ in the roots but I don’t quite understand the ‘u’ solution.Hello,
