Question 16522
Congratulations on being able to write this in algebra.com notation!  The first step is to factor the numerator and denominator:


{{{(n^2+10n+25)/(40+3n-n^2)}}}

{{{((n+5)*(n+5))/((5+ n)*(8-n))}}}


Divide out the (n+5) factor in the numerator with the (5+n) factor in the denominator.  The result is the answer:

{{{(n+5)/(8-n)}}}
