Answer/Discussion to 1a

-3

Since this is a constant term, then the degree is 0.

(return to problem 1a)

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.

(return to problem 1b)

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.

(return to problem 2a)

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.

(return to problem 2b)

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.

(return to problem 2c)

Answer/Discussion to 3a

*Remove the (  )
*Add like terms together

(return to problem 3a)

Answer/Discussion to 3b

*Dist. the - through second ( )
*Combine like terms

(return to problem 3b)
