Determine the signs of the roots of the equation (if they exist) without solving the equation:
\n" ); document.write( " $\"x%5E2-2x-1=0\"$
\n" ); document.write( "The discriminant
\n" ); document.write( " $\"-2%5E2+-+4%2A1%2A-1\"$
\n" ); document.write( "4 + 4 = 8
\n" ); document.write( "Positive means two distinct real roots, not necessarily both positive \n" ); document.write( "

\n" );
