Hey there :)

9( n - 4 ) - 4n ( n - 4 )
We can take ( n - 4 ) as common as both are getting multiplied by ( n - 4 )

We can join 9 - 4n together

Therefore, the final answer will be ( n - 4 )( 9 - 4n )

9(n-4) - 4n(n-4)

Here you see that there are two (n-4). So you have to factor (n-4).

It gives : (n - 4) (9 - 4n).

In short, the answer would be the option A.

Hope this helps !
