In a quadratic equation, the discriminant is that quantity that appears under the radical sign of the quadratic formula.
\n" ); document.write( "Here's the quadratic formula: \"x+=+%28-b%2B-sqrt%28b%5E2-4ac%29%29%2F2a\"
\n" ); document.write( "The discriminant is: \"b%5E2-4ac\" and, for your problem, this would be:
\n" ); document.write( "\"10%5E2-4%2815%29%28-1%29\" and when this is evaluated, it is:
\n" ); document.write( "\"100-%28-60%29+=+160\"
\n" ); document.write( "The discriminant is a positive quantity, the the quadratic equation will have two real roots.
\n" ); document.write( "Notice that the discriminant does not conain a variable, as you have shown in your answer! \n" ); document.write( "
\n" );
