°° Let's see -

(3n - 2m) ^2 is equal to (3n - 2m) (3n - 2m) =

9n ^2 - 6mn - 6mn + 4m ^2 =

9n ^2  - 12mn + 4m ^2

So, therefore, choice D) 9n ^2 - 12mn + 4m ^2 is the correct answer. :)

[tex](3n - 2m)^2 \\ \\ (3n)^2 - 2 \times 3n \times 2m + (2m)^2 \\ \\ 3^2n^2 - 2 \times 3n \times 2m + (2m)^2 \\ \\ 9n^2 - 2 \times 3n \times 2m + (2m)^2 \\ \\ 9n^2 - 2 \times 3n \times 2m + 2^2m^2 \\ \\ 9n^2 - 2 \times 3n \times 2m + 4m^2 \\ \\ 9n^2 - 12mn + 4m^2[/tex]

The final result would be, D) 9n² - 12mn + 4m².
