    Assignment:Find the solution set of inequality ((40*n+193.44)*((n-4.86)^2))/6+575.26*n+283.9036-1.2*(258.32*n+449.43+((n^2)*(13.33*n+245.58069))/6) ≥0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( ( 40 * n + 193.44 ) * ( ( n - 4.86 ) ^ 2 ) ) / 6 + 575.26 * n + 283.9036 - 1.2 * ( 258.32 * n + 449.43 + ( ( n ^ 2 ) * ( 13.33 * n + 245.58069 ) ) / 6 ) ≥0         (1)

---

    From inequality(1)：
         -1.847539 ≤ n ≤ 3.685589 或  n ≥ 18.577582

---

    The final solution set is :
         -1.847539 ≤ n ≤ 3.685589 或  n ≥ 18.577582
