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.
