Evaluate:

n
n-2 (expression should be in large brackets)

I got n! /n-2! 2! .

I know this is wrong but am not sure what to do next.

To evaluate the expression n(n-2) and express it in large brackets, you can follow the steps below:

Step 1: Simplify the expression n(n-2) by performing the multiplication.

n(n-2) = n^2 - 2n

Step 2: Enclose the simplified expression in large brackets.


⎨ n^2 - 2n


That's the final evaluation of the expression n(n-2) in large brackets.
