Mahcad 15 knows "optimize": Right click the expression an from the pop up menu chose "Optimize".

 

You get better precision with numeric calculations if you decrease the value of the system variable "TOL".

Set it to something like 10^-10. Either from the menu in "Tools"-"Worksheet Options"-"Built-In Variables" or just type TOL:=10^-10 at the top of the sheet (or use a global assignment).
