document.write( "\r\n" );
document.write( "In our case,  the denominator is  (3x^2 -12), and it factors this way\r\n" );
document.write( "\r\n" );
document.write( "    3x^2 - 12 = 3*(x^2-4) = 3*(x-2)*(x+2).\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "So the roots are  2 and -2.  They are excluded values.      ANSWER\r\n" );
