You can put this solution on YOUR website!
use property a^(-1)=1/a to simplify fraction
%28ab%5E%28-1%29%2B1%29%2F%28a%5E%28-1%29b%2B1%29= %28%28a%2Fb%29%2B1%29%2F%28%28b%2Fa%29%2B1%29 =
find common denominator for a/b+1 and b/a+1
=%28a%2Fb%2Bb%2Fb%29%2F%28b%2Fa%2Ba%2Fa%29=+%28%28a%2Bb%29%2Fb%29%2F%28%28a%2Bb%29%2Fa%29=
to divide to fractions it means you have to multiply first by inverse of second
=%28%28a%2Bb%29%2Fb%29%2A%28a%2F%28a%2Bb%29%29=a%2Fb <---answer
