[ 1/1Inequality]
    Assignment:Find the solution set of inequality (x^2-4x-5)/(3x^2-10x+8) ≥0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( x ^ 2 - 4 * x - 5 ) / ( 3 * x ^ 2 - 10 * x + 8 ) ≥0         (1)
        From the definition field of divisor
         3 * x ^ 2 - 10 * x + 8 ≠ 0        (2 )

---

    From inequality(1)：
         x ≤ -1 或  1.333333 ≤ x ≤ 2 或  x ≥ 5
    From inequality(2)：
         x < 4/3 或  4/3 < x < 2 或  x ＞ 2

---

    From inequalities (1) and (2)
         x ≤ -1 或  4/3 < x < 2 或  x ≥ 5    (3)

---

    The final solution set is :
         x ≤ -1 或  4/3 < x < 2 或  x ≥ 5
