Error solving equation in CAS

[Helge Gabert]

Please state your equation again.

You shouldn't need any "{}" nor "[]". Are the "," thousand separators, or are they decimal points "."? All "X" should be "x" in CAS.

In CAS, try fsolve(your equation, x). You can also use a starting value, or interval (see help for fsolve).

In Home, try FNROOT with a starting guess close to the second solution (again, see help for FNROOT). Here "X" is OK.
