You can put this solution on YOUR website!
(n!n^2-n!)/((n-1)(n+1))\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "(n!(n^2-1))/((n-1)(n+1))\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "(n!(n-1)(n+1))/((n-1)(n+1))\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "n!\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So the expression simplifies to n!\r
