Answer 2

It looks like you have a polynomial expression that you want to multiply. The expression you've provided is:

(3n^2 – 2nm – m) * (3n - 2m)

To multiply these two expressions, you can use the distributive property (also known as the FOIL method for binomials):

(3n^2 – 2nm – m) * (3n - 2m) = 3n^2 * 3n + 3n^2 * (-2m) - 2nm * 3n - 2nm * (-2m) - m * 3n + m * 2m = 9n^3 - 6n^2m - 6n^2m + 4m^2 - 3mn + 2m^2 = 9n^3 - 12n^2m + 4m^2 - 3mn + 2m^2

So, the result of the multiplication is: 9n^3 - 12n^2m + 4m^2 - 3mn + 2m^2
