Dear All,

What is the meaning of the help of Factor:

Factor[poly,Extension->Automatic] will extend the domain of
coefficients to include any algebraic numbers that appear in poly.  =BB

if

Factor[x^2 - 2, Extension -> Automatic]

does not seem to work in the same way as

Factor[x^2 - 2, Extension -> Sqrt[2]]

Thanks,

J=E1nos
