Answer:

Explanation:
All the other expressions can be factorized. Let's see why:
1) 
This is the sum of the cubes, and this can be factorized as follows:

In this case, a=m and b=1, so we can factorize as

2) 
This is the difference between two cubes, and this can be factorized as follows:

In this case, a=m and b=1, so we can factorize as

3) 
This is the difference between two square numbers, and it can be factorized as follows

In this case, a=m and b=1, so we can factorize as
