    Assignment:Find the solution set of inequality 23x^3-330x^2+1200x+1100+1800x <1.5280*5000 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        23 * x ^ 3 - 330 * x ^ 2 + 1200 * x + 1100 + 1800 * x <1.5280 * 5000         (1)

---

    From inequality(1)：
         x < 2.932702

---

    The final solution set is :
         x < 2.932702
