    Assignment:Find the solution set of inequality 626.02*n+476.3368+((20*n+92.12)*((n-5.09)^2))/3-1.2*(313.06*n+700.9425+(13.33*n^3+242.46273*n^2)/6) ≥0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        626.02 * n + 476.3368 + ( ( 20 * n + 92.12 ) * ( ( n - 5.09 ) ^ 2 ) ) / 3 - 1.2 * ( 313.06 * n + 700.9425 + ( 13.33 * n ^ 3 + 242.46273 * n ^ 2 ) / 6 ) ≥0         (1)

---

    From inequality(1)：
         -1.64368 ≤ n ≤ 3.319505 或  n ≥ 19.733743

---

    The final solution set is :
         -1.64368 ≤ n ≤ 3.319505 或  n ≥ 19.733743
