$\"%283a%2F%28a-4%29%29-%284%2F%283%28a-4%29%29%29\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"%283%2F3%29%283a%2F%28a-4%29%29-%284%2F%283%28a-4%29%29%29\"$ multiplied by a 1/1, 3/3=1
\n" ); document.write( " $\"%289a%2F%283%28a-4%29%29%29-%284%2F%283%28a-4%29%29%29\"$ both have common denoms so subtract numerators
