\n" ); document.write( "The answer you show from the book doesn't make any sense.
\n" ); document.write( "(1) The answer you show is an unsimplified rational expression; it could never be the final simplified answer to a problem.
\n" ); document.write( "(2) With all those binomials in all the rational expressions in the original problem, you aren't going to end up with a monomial answer.

\n" ); document.write( "It looks as if you are doing the right things, for the problem as you show it.

\n" ); document.write( "Are you sure you have shown the problem correctly? It might simplify considerably if the addition between the first two expressions were a multiplication instead....
