(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

[7.02] Find the difference of (−5x2 − 4x3 − 3) − (9x3 + 3x − 8x2). Be sure to show all of your work in a neat and organized fashion.

Use the ^ (shift 6) symbol to show an exponent. For example, x squared can be written as x^2.
