 Answer/Discussion to 1a -3 Since this is a constant term, then the degree is 0.

 Answer/Discussion to 1b Since the degree is the sum of the variable exponents and it looks like we have a 7 and a 1 as our exponents, the degree would have to be 7 + 1 = 8.

 Answer/Discussion to 2a Since the degree of the polynomial is the highest degree of all the terms, it looks like the degree is 3. Since there are two terms, this is a binomial.

 Answer/Discussion to 2b Since the degree of the polynomial is the highest degree of all the terms, it looks like the degree is 1.  Since there is one term, this is a monomial.

 Answer/Discussion to 2c Since the degree of the polynomial is the highest degree of all the terms, it looks like the degree is 2.  Since there are three terms, this is a trinomial.
