The standard form of the polynomial function is [tex]\rm -6m^6+n^6+7mn^5+14m^2^4-5m^3n^3[/tex].
.
The polynomial given is
[tex]\rm 8mn^5 - 2m^6 +5m^2n^4 -m^3n^3 n^6 - 4m^6 +9m^2n^4 - mn^5 -4m^3n^3[/tex]
An expression of more than two algebraic terms, especially the sum of several terms that contain different powers of the same variable(s).
Let us rearrange the expression as;
[tex]\rm 8mn^5 - 2m^6 +5m^2n^4 -m^3n^3+ n^6 - 4m^6 +9m^2n^4 - mn^5 -4m^3n^3\\\\-2m^6- 4m^6 + n^6+8mn^5- mn^5 +5m^2n^4 +9m^2n^4-m^3n^3 -4m^3n^3[/tex]
Simplifying the above expression as;
[tex]\rm -6m^6+n^6+7mn^5+14m^2^4-5m^3n^3[/tex]
The above expression of the polynomial function is in its standard form.
Hence, the standard form of the polynomial function is [tex]\rm -6m^6+n^6+7mn^5+14m^2^4-5m^3n^3[/tex].
