Which polynomial correctly combines the like term and express the given polynomial in standard form
ankoles [38]

Answer:

8mn^5 - 2m^6 + 5m^2n^4 - m^3n^3 + n^6 - 4m^6 + 9m^2n^4 - mn^5 - 4m^3n^3 = -6m^6  - mn^5 - 5m^3n^3 + 14m^2n^4 + 8mn^5  + n^6

Step-by-step explanation:

Given

8mn^5 - 2m^6 + 5m^2n^4 - m^3n^3 + n^6 - 4m^6 + 9m^2n^4 - mn^5 - 4m^3n^3

Required

Correctly combine the like terms

We have:

8mn^5 - 2m^6 + 5m^2n^4 - m^3n^3 + n^6 - 4m^6 + 9m^2n^4 - mn^5 - 4m^3n^3

Collect like terms (in decreasing degrees of m)

- 2m^6 - 4m^6  - mn^5- m^3n^3  - 4m^3n^3+ 5m^2n^4  + 9m^2n^4 + 8mn^5  + n^6

-6m^6  - mn^5 - 5m^3n^3 + 14m^2n^4 + 8mn^5  + n^6

So:

8mn^5 - 2m^6 + 5m^2n^4 - m^3n^3 + n^6 - 4m^6 + 9m^2n^4 - mn^5 - 4m^3n^3 = -6m^6  - mn^5 - 5m^3n^3 + 14m^2n^4 + 8mn^5  + n^6
