Hi,I tried to check is a polynomial have a variable, ussing the function 
PolynomialQ.

In[1]:=p = x^3 - 2*x^2 + x - 1;
In[2]:=PolynomialQ[p, x]
Out[2]=True
In[3]:=PolynomialQ[p, y]
Out[3]=True
In[4]:=PolynomialQ[p, z^2]
Out[4]=True
In[5]:=PolynomialQ[p, {u, v}]
Out[5]=True

What is the thing I am doing wrong?

Regards.Juan
