sorry I copied the question wrong

neverendingcycle · Answer

its okay

4everaddicted2anime · Answer

First lets distribute the 2m^2 to (-3m+4m^2)
You should get
$$-6m^2+8m^4$$
That was only the first part of the problem.
The next part is -(3m)^3
This part should come out to
$$-27m^3$$
Then you need to put the two parts together to get
$$-6m^2+8m^4-27m^3$$
