You can put this solution on YOUR website!
calculate the discriminant __ b^2-4ac (it is the quantity under the square root in the quadratic formula)\r

\n" ); document.write( "\n" ); document.write( "if >0 then 2 points (roots)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "if =0 then 1 point (double root)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "if <0 then 0 points (no real roots) \n" ); document.write( "
