{{{
sage: P.<x> = ZZ[]
sage: (4*x).parent()
Univariate Polynomial Ring in x over Integer Ring
sage: (4*x).is_squarefree()
True
sage: (QQ(4)*x).is_squarefree()
True
sage: 4.is_squarefree()
False
sage: P(4).is_squarefree()
True
}}}
The first and last should of course be False, as {{{2^2}}} is a divisor.
