If you keep complex mode unchecked, it does not mean you will stay in the real domain. For example, sqrt(1) will return i if complex is unchecked. Checking complex just says to the CAS that factor and associated functions should behave like if coefficients were complex even if they are all reals. Why x^(1/3) is a complex number if x<0 ? q is odd …
