write them as a quadratic, like $\"ax%5E2+%2B+bx+%2B+c+=+0\"$ .\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Then work out $\"b%5E2+-+4ac\"$ .\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "If $\"b%5E2+-+4ac\"$ > 0 --> 2 real roots
\n" ); document.write( "If $\"b%5E2+-+4ac\"$ = 0 --> 1 real root
\n" ); document.write( "If $\"b%5E2+-+4ac\"$ < 0 --> 0 real roots... enter the realm of Complex numbers.\r
\n" ); document.write( "
