X⁴ + 1/x⁴ = 119

(x² + 1/x² )² = x⁴ + 1/x⁴ + 2 = 119 + 2 = 121

x² + 1/x² = √121 = 11

(x - 1/x)² = x² + 1/x² - 2  = 11 - 2 = 9

x - 1/x  = +- √9 = + 3  or - 3

case 1:  x - 1/x = 3

     (x - 1/x)³ = x³ - 1/x³ - 3 x * 1/x (x - 1/x)

         27    = x³ - 1/x³ - 3 * 3

       x³ - 1/x³ =   36

case 2:  x - 1/x = -3

     x³ - 1/x³ = -27 - 9 = -36
