[ 1/1Inequality]
    Assignment:Find the solution set of inequality 862+587n+(214n+22n^2)*(214n+7.3n^2)/(428+44n)+(13.6+n)*41+(8.9+n)*319.5-1.2[3628+1057n+(285n+3.7n^2)*(285n+1.23n^2)/(285+3.7n)] >= 0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        862 + 587 * n + ( 214 * n + 22 * n ^ 2 ) * ( 214 * n + 7.3 * n ^ 2 ) / ( 428 + 44 * n ) + ( 13.6 + n ) * 41 + ( 8.9 + n ) * 319.5 - 1.2 * ( 3628 + 1057 * n + ( 285 * n + 3.7 * n ^ 2 ) * ( 285 * n + 1.23 * n ^ 2 ) / ( 285 + 3.7 * n ) ) >= 0         (1)
        From the definition field of divisor
         428 + 44 * x ≠ 0        (2 )
        From the definition field of divisor
         285 + 3.7 * x ≠ 0        (3 )

---

    From inequality(1)：
         -0.953428 ≤ n ≤ -0.398707 或  n ≥ 109.447811
    From inequality(2)：
         n < -107/11 或  n ＞ -107/11
    From inequality(3)：
         n < -2850/37 或  n ＞ -2850/37

---

    From inequalities (1) and (2)
         -0.953428 ≤ n ≤ -0.398707 或  n ≥ 109.447811    (4)
    From inequalities (3) and (4)
         -0.953428 ≤ n ≤ -0.398707 或  n ≥ 109.447811    (5)

---

    The final solution set is :
         -0.953428 ≤ n ≤ -0.398707 或  n ≥ 109.447811
