\n" ); document.write( "\n" ); document.write( "This will have no rational roots. There are two irrational real roots, so those are what you want to find. Use what you might know of upper and lower bound testing, or find two values around which the sign for the function changes. Use whatever numerical techniques you have which let you get the roots as accurately as you need.\r
