See explanation.

To write a poolynomial in standard form you have to order its terms by decreasing powers of the variable, so here it will be:

$9 x^{2} - 11 x + 1$ $9x^2-11x+1$

Now when the polynomial is in the standard form we can say that it is:

a trinomial - because it has 3 terms
a polynomial of the second degree - because the highest exponent of $x$ $x$ is $2$ $2$ .
