    Assignment:Find the solution set of inequality 4000x(x-2)+1000x <30000 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        4000 * x * ( x - 2 ) + 1000 * x <30000         (1)

---

    From inequality(1)：
         -2 < x < 15/4

---

    The final solution set is :
