    Assignment:Find the solution set of inequality -2048.7065+1146.8248n+n^2/3×(776.346+19.119n)×(2329.038+38.238n)/(1552.692+38.238n)-0.4×n^2×(254.939+4.766n)×（764.817+9.531n）/（509.878+9.531n） ≥0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        -2048.7065 + 1146.8248 * n + n ^ 2 / 3 × ( 776.346 + 19.119 * n ) × ( 2329.038 + 38.238 * n ) / ( 1552.692 + 38.238 * n ) - 0.4 × n ^ 2 × ( 254.939 + 4.766 * n ) × ( 764.817 + 9.531 * n ) / ( 509.878 + 9.531 * n ) ≥0         (1)
        From the definition field of divisor
         1552.692 + 38.238 * x ≠ 0        (2 )
        From the definition field of divisor
         509.878 + 9.531 * x ≠ 0        (3 )

---

    From inequality(1)：
         -46.997472 ≤ n ≤ -7.055573 或  n ≥ 1.383521
    From inequality(2)：
         n < -40.605994 或  n ＞ -40.605994
    From inequality(3)：
         n < -53.4968 或  n ＞ -53.4968

---

    From inequalities (1) and (2)
         -46.997472 ≤ n < -40.605994 或  -40.605994 < n ≤ -7.055573 或  n ≥ 1.383521    (4)
    From inequalities (3) and (4)
         -46.997472 ≤ n < -40.605994 或  -40.605994 < n ≤ -7.055573 或  n ≥ 1.383521    (5)

---

    The final solution set is :
         -46.997472 ≤ n < -40.605994 或  -40.605994 < n ≤ -7.055573 或  n ≥ 1.383521
