Here is the problem:
\n" ); document.write( "\"4xy%2F%28x%5E2-y%5E2%29+%2B+%28x-y%29%2F%28x%2By%29\"
\n" ); document.write( "step 1 - find the common denominator is x^2 - y^2 or (x+y)(x-y)
\n" ); document.write( "step 2 - multiply second fraction by (x-y) to get
\n" ); document.write( "\"4xy%2F%28x%5E2-y%5E2%29+%2B+%28x-y%29%28x-y%29%2F%28x%5E2-y%5E2%29\"
\n" ); document.write( "step 3 - distribute numerator and combine like terms to get
\n" ); document.write( "\"%28x%5E2%2B2xy%2By%5E2%29%2F%28x%5E2-y%5E2%29\"
\n" ); document.write( "factor the numerator and denominator and reduce to get
\n" ); document.write( "\"%28%28x%2By%29%5E2%29%2F%28%28x%2By%29%28x-y%29%29\"
\n" ); document.write( "and then
\n" ); document.write( "\"%28x%2By%29%2F%28x-y%29\"
\n" ); document.write( "
\n" );
