\"%287-a%29%284-3a%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"7%284-3a%29-a%284-3a%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"28-21a-4a%2B3a%5E2\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"28-25a%2B3a%5E2\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"3a%5E2-25a%2B28\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So \"%287-a%29%284-3a%29\" multiplies out to \"3a%5E2-25a%2B28\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "In other words, \"%287-a%29%284-3a%29=3a%5E2-25a%2B28\" for all values of 'a'.\r
