Answer:
Step-by-step explanation:
I'm going to take a leap here and say that the -41^2 should be a -41t^2 and that the expression should look like this:

A term is a combination of variables and numbers separated by either a plus or a minus from another combination of variables and numbers. We have 3 terms: -41t^2 is one; -13t is another; 9 is the last. So this is a trinomial.
The degree of a polynomial is equal to the degree of the highest degree'd term. Since the leading term has a power of 2 and that's the highest degree of all the terms, this is a second degree polynomial, or a quadratic, to be more specific.
