\n" ); document.write( "I do this just by trying factors of 15 and
\n" ); document.write( "moving the factors anf the + and - signs
\n" ); document.write( "around until it works
\n" ); document.write( "If the equation were $\"3x%5E2+%2B+44x+-+15\"$
\n" ); document.write( "I would need big numbers, so I'd try 15 and 1 for
