school - $q(x)^2=(x+1)^2=x^2+2x+1$, which is different from   $x^2+1$.  \begin{Example}  When we learn at school how to rise raise  the binomial $x+1$ to acertain  power $\alpha$, we learn the construction of the so called Pascal's (or Tartaglia's) Triangle. We can repeat the same construction on $\Fb[x]$:  \\  $(x+1)^0 = 1 \rightarrow \mathbf{1}$\\
