Question

1. A.
2. −9x + 8x² + 7x⁴ − 5 − x⁵
3. 
   
4. B.
5. 8x² − 5 + 7x⁴ − 9x − x⁵
6. 
   
7. C.
8. −x⁵ + 7x⁴ + 8x² − 9x − 5
9. 
   
10. D.
11. −5 − 9x + 8x² + 7x⁴ − x⁵

Answer 1

Answer c. You arrange in order of the power.

Answer 2

standard form means put the terms in order from greatest exponent to least exponent:

8x² - 5 + 7x⁴ - 9x - x⁵

- x⁵ + 7x⁴ + 8x² - 9x - 5

So the answer is C.
