check markAnswer/Discussion to 1a

-10
 

Since the degree of the polynomial is the highest degree of all the terms, it looks like the degree is 0. 

Since there is one term, this is a monomial.
 

(return to problem 1a)


 

check markAnswer/Discussion to 1b

prob 1b
 

Since the degree of the polynomial is the highest degree of all the terms, it looks like the degree is 4. 

Since there are three terms, this is a trinomial.
 

(return to problem 1b)


 

check markAnswer/Discussion to 1c

prob 1c
 

Since the degree of the polynomial is the highest degree of all the terms, it looks like the degree is 2. 

Make sure that you don't fall into the trap of thinking it is always the degree of the first term.  This polynomial is not written in standard form (descending order).  So we had to actually go to the second term to get the highest degree.
 

Since there are two terms, this is a binomial.
 

(return to problem 1c)
