Answer 1

Can you double check my work, and make sure that I did everything correct?


Part 1
Choose 3 of the polynomials from the list below and classify each one by degree and number of terms.
(2 points each)
1. 9x2yz
2. 18x2 + 5ab – 6y
3. 8a – 5
4. 4x3 + 3x2 – x – 4
5. x + 2xyz
6. 3x + y + z
7. 2x3y + y2x – 3x + 4
8. 6x2

Polynomial 1 has a degree of 4 and it is a monomial.
Polynomial 8 has a degree of 2 and is a monomial.
Polynomial 2 has a degree of 2 and is a trinomial.

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)
1. 3a3b – 4ab2 + a2
2. –8x2y2 + 10xy4 – 6x2y

Polynomial 1 is written in standard form. We know this because it is written with the exponents from greatest to least (4, 3, and 2).
Polynomial 2 is not written in standard form. It should be written as:
10xy4 – 8x2y2 – 6x2y. It should be written as this because; the first one is 5, the second one is 4 and the third one is 3.

Answer 2

This document is a little more organized. :)
