checkAnswer/Discussion to 1a

-3

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

(return to problem 1a)

 


 

checkAnswer/Discussion to 1b
problem 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)

 


 

checkAnswer/Discussion to 2a

problem 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)

 


 

checkAnswer/Discussion to 2b

problem 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)


 

checkAnswer/Discussion to 2c

problem 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)


 

checkAnswer/Discussion to 3a

If problem 3a, find P(-3)
 

ad3a
*Replace x with -3

*Exponent first
*Subtraction
 
 

(return to problem 3a)

 


 

checkAnswer/Discussion to 4a

problem 4a
 

ad4a

*Remove the (  )
*Add like terms together

 
(return to problem 4a)


 

checkAnswer/Discussion to 4b

problem 4b
 

ad4b

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

 
(return to problem 4b)
