    Assignment:Find the solution set of inequality 200(x-10)^2+66000 <= 540000 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        200 * ( x - 10 ) ^ 2 + 66000 <= 540000         (1)

---

    From inequality(1)：
         -38.682646 ≤ x ≤ 58.682646

---

    The final solution set is :
         -38.682646 ≤ x ≤ 58.682646
