    Assignment:Find the solution set of inequality -(5*x^2+x-6)(x^2-2x-8) >0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        -( 5 * x ^ 2 + x - 6 ) * ( x ^ 2 - 2 * x - 8 ) >0         (1)

---

    From inequality(1)：
         -2 < x < -6/5 或  1 < x < 4

---

    The final solution set is :
         -2 < x < -6/5 或  1 < x < 4
