Question

Choose 3 of the polynomials from the list below and classify each one by degree and number of terms.
(2 points each)

1) 9x2yz
Term = 1


2) 18x2 + 5ab – 6y
Term = 3


3) 8a – 5
Term = 2


4) 4x3 + 3x2 – x – 4
Term = 4


5) x + 2xyz
Term = 2


6) 3x + y + z
Term = 3

7) 2x3y + y2x – 3x + 4
Term = 4


8) 6x2
Term = 1

I just need help finding the Degrees, its the only thing that confuses me

Answer 1

The degree of a polynomial is the number of the highest exponent.

Answer 2

Okay, well I only need 1, 5 and 7,

for 1 ) I put 2 but its 1
for 5) 1 but idk the correct.
for 7, i put 3 ... but idk that one either.

Plz tell me is 1 correct. and the 5 and 7..

Answer 3

For polynomials in two or more variables, the degree of a term is the sum of the exponents of the variables in the term; the degree of the polynomial is again the maximum of the degrees of all terms in the polynomial.

Answer 4

Ahh. Thank you.

Answer 5

1) 9x2yz
Degree=4
x=2
y=1
z=1
2+1+1=4

5) x + 2xyz
x
x=1
--
2xyz
x=1
y=1
z=1
1+1+1=3

Degree=3

7) 2x3y + y2x – 3x + 4
2x^3y
x=3
y=1
3+1=4
--
y^2x
y=2
x=1
2+1=3
--
3x
x=1

Degree=4

Answer 6

Thank you so much :)
