Question

Part 1

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

9x2yz
18x2 + 5ab – 6y
8a – 5
4x3 + 3x2 – x – 4
x + 2xyz
3x + y + z
2x3y + y2x – 3x + 4
6x2
Part 2

Explain whether the polynomials below are written in standard form. If not, use complete sentences to explain how to write the polynomial in standard form. (2 points each)

3a3b – 4ab2 + a2
–8x2y2 + 10xy4 – 6x2y

Answer 1

18x2 + 5ab – 6y
2nd degree, 3 terms - trinomial

8a - 5
degree 1 - 2 terms binomial

x + 2xyz
3rd degree, 2 terms

Answer 2

second part:
i think these should be written with highest exponent first:

3a3b – 4ab2 + a2

= -4ab^2 + 3a3b + a^2

–8x2y2 + 10xy4 – 6x2y

= 10 xy^4 - 8x^2y^2 - 6x2y
