[ 1/1Inequality]
    Assignment:Find the solution set of inequality 1/10*{1+[1-(1-a)^10]*(186.89*a^2+54.23*a+12.8)/(17*a^2+5*a+2)} <[1/10+1-(1-a)^10] .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        1 / 10 * ( 1 + ( 1 - ( 1 - a ) ^ 10 ) * ( 186.89 * a ^ 2 + 54.23 * a + 12.8 ) / ( 17 * a ^ 2 + 5 * a + 2 ) ) < ( 1 / 10 + 1 - ( 1 - a ) ^ 10 )         (1)
        From the definition field of divisor
         17 * x ^ 2 + 5 * x + 2 ≠ 0        (2 )

---

    From inequality(1)：
         a < -0.790029 或  0 < a < 0.539585 或  a ＞ 2
    From inequality(2)：
         a ∈ R （R为全体实数），即在实数范围内，不等式恒成立！

---

    From inequalities (1) and (2)
         a < -0.790029 或  0 < a < 0.539585 或  a ＞ 2    (3)

---

    The final solution set is :
         a < -0.790029 或  0 < a < 0.539585 或  a ＞ 2
