[ 1/1Inequality]
    Assignment:Find the solution set of inequality (x+2)/(x^2-5x-6) >= 0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality:
         ( x + 2 ) / ( x ^ 2 - 5 * x - 6 ) >= 0         (1)
        From the definition field of divisor
         x ^ 2 - 5 * x - 6 ≠ 0        (2 )

    From inequality(1):
         -2 ≤ x ≤ -1 或  x ≥ 6
    From inequality(2):
         x < -1 或  -1 < x < 6 或  x > 6

    From inequalities (1) and (2)
         -2 ≤ x < -1 或  x > 6    (3)

    The final solution set is :

         -2 ≤ x < -1 或  x > 6
