Question 87799
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)
{{{(4(n+1)+2(3n)+2(3))/(3n(n+1))}}}
After simplifying, you get..
{{{(10n+10)/(3n(n+1))}}}
Factor out 10 from (10n+10) and you get..
{{{(10(n+1))/(3n(n+1))}}}
The (n+1) terms cancel and your answer is..
{{{10/3n)}}}

Hope that helps
