You can put this solution on YOUR website!
\"x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+\" this is the formula they are using .... the portion under the root is called the discriminant.\r
\n" ); document.write( "\n" ); document.write( "When you calculate this portion you will come out with one of three numbers: A positive, a negative or zero.
\n" ); document.write( "if the number is positive, there are two roots (places where the graph crosses the x-axis)
\n" ); document.write( "if the number is zero there is only one solution, and the parabala just touches the x-axis
\n" ); document.write( "if the number is negative, there are no real solutions and the graph does not cross the x-axis
\n" ); document.write( "
\n" );
