Answer 2

Answer:

C. m^2 - 7

Step-by-step explanation:

First, remove the parentheses. They are not needed, as we will be grouping like terms:

m^2 - m - 3 + m - 4

Now, we will group terms that are similar, or the same. Here, we can group both the -m and the m. These terms cancel out.

We can also group the constants, or numbers that don't have a variable attached to them:

m^2 - m + m - 3 - 4

Which, further simplifies into:

m^2 - 3 - 4

^^^Here, we cancelled out both of the m

Now, we subtract the -3 and -4:

m^2 - 7

This equation cannot be further simplified, and the answer option C matches.

Hope this helps!
