Still clueless though

Answer 1

from the answer you write this expression still miss the bracket

 

  6/(n+4) - 2/(n-4)

 

= 6 (n - 4) / [(n + 4)(n - 4)] - 2 (n + 4) / [(n + 4)(n - 4)]

 

= (6n - 24) / [(n + 4)(n - 4)] - (2n + 8) / [(n + 4)(n - 4)]

 

= (6n - 24 - 2n - 8) / [(n + 4)(n - 4)]

 

= (4n - 32) / [(n + 4)(n - 4)]
