Note: property change

changed:
-
\begin{axiom}
factor(simplify((1+x)^3))
\end{axiom}
vs.
\begin{axiom}
factor((1+x)^3)
\end{axiom}

simplify changes the type to 'Expression Integer', where the original was 'Polynomial Integer'.

Why does factor refuse to factor an Expression Integer but
succeeds with Polynomial Integer?
\begin{axiom}
simplify((1+x)^3)
factor(%::Polynomial Integer)
\end{axiom}
