Simplify (3n - 2m) 2 = ? a. 6n2 - 12mn - 4m2 b. 9n2 - 12mn - 4m2 c. 9n2 12mn 4m2 d. 9n2 - 12mn 4m2

If you would like to simplify (3n - 2m) ^2, you can do this using the following steps:

(3n - 2m) ^2 = 3^2 * n^2 - 3 * 2 * 2 * n * m + 2^2 * m^2 = 9n^2 - 12nm + 4m^2

The correct result would be d. 9n^2 - 12nm + 4m^2.
