You can put this solution on YOUR website!
The graph y = ax^2 + bx + c is a parabola and where a, b and c are real:\r
\n" ); document.write( "\n" ); document.write( "has two different real roots when the discriminant is greater than 0 and the graph cuts across the x-axis twice.\r
\n" ); document.write( "\n" ); document.write( "has two equal real roots when the discriminant is equal to 0 and the graph touches the x-axis in one place only.\r
\n" ); document.write( "\n" ); document.write( "has two conjugate complex roots when the discriminant is less than 0 and the graph doesn’t cross the x-axis.
