Best ResponseYou've already chosen the best response.0First, we make (ab) = (ba): [1/(ab)  4/(ab)]  8/(a+b)  (11a  5b)/(b^2a^2) Subtracting the first two fractions: 3/(ab)  8/(a+b))  (11a  5b)/(b^2a^2) Gathering the first two fractions into one fraction: (3a  3b  8a + 8b)/(ab)(a+b)  (11a  5b)/(b^2a^2) Equals: (11a + 5b)/(a^2  b^2) Doing the same as the first step: (11a  5b)/(b^2  a^2)

Best ResponseYou've already chosen the best response.0Of course, note that: (ba)(b+a) = (b^2  a^2), right?
