You can put this solution on YOUR website!
factor the 7:
\n" ); document.write( "1 7
\n" ); document.write( ".
\n" ); document.write( "factor the 42:
\n" ); document.write( "2 3 7
\n" ); document.write( ".
\n" ); document.write( "Look for \"some\" combination that will give you 49:
\n" ); document.write( "7*6=42
\n" ); document.write( "1*7 = 7
\n" ); document.write( "42 + 7 = 49!
\n" ); document.write( ".
\n" ); document.write( "(x+6)(7x+7) \n" ); document.write( "

\n" );
