Remove the common factor found in each term.
Then divide each term by that common factor.
The common factor found in each term is 3.
Do you see 3 in each term?
3m^2 divide by 3 = m^2
3n^2 divide by 3 = n^2
We now have this: 3(m^2 - n^2)
Inside the parentheses, we have what is called the difference of two perfect squares. We can factor that out to be (m - n)(m + n).
Final answer: 3(m - n)(m + n)
NOTICE: The final answer has 3 factors. Do you see the factors?
