6m^5 + 3 + m^3 - 4m) - (m^5 + 2m^3 - 4m + 6) =

5m^5-m^3-3

Step-by-step explanation:

What you do is you have to distribute the negative sign into the equation.

-m^5-2m^3+4m-6. Next, you will either add or subtract from the other equation.

6m^5-m^5=5m^5.

m^3-2m^3=-m^3.

-4m+4m=0m or you don't put anything.

3-6=-3. Then you put it all together to get.

5m^5-m^3-3 as your answer.
