If the first question is entered correctly, the answer should be 4. The first two terms cancel each other.
82. Factor n out of the third term
=4/3n+2/n+1+2/n(n+1)
your common denominator is 3n(n+1)
%284%28n%2B1%29%2B2%283n%29%2B2%283%29%29%2F%283n%28n%2B1%29%29
After simplifying, you get..
%2810n%2B10%29%2F%283n%28n%2B1%29%29
Factor out 10 from (10n+10) and you get..
%2810%28n%2B1%29%29%2F%283n%28n%2B1%29%29
The (n+1) terms cancel and your answer is..
10%2F3n%29
Hope that helps
