    Assignment:Find the solution set of inequality 0.7*(0.6*a^2-0.7/a)/2/(0.7/a+0.3*a^2) >0.49*(0.7/a+0.3*a^2) .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        0.7 * ( 0.6 * a ^ 2 - 0.7 / a ) / 2 / ( 0.7 / a + 0.3 * a ^ 2 ) >0.49 * ( 0.7 / a + 0.3 * a ^ 2 )         (1)
        From the definition field of divisor
        x ≠ 0        (2 )
        From the definition field of divisor
        x ≠ 0        (3 )
        From the definition field of divisor
         0.7 / x + 0.3 * x ^ 2 ≠ 0        (4 )
        From the definition field of divisor
        x ≠ 0        (5 )

    From inequality(1)：
         -2.598966 < a < -1.326352 或  -0.635846 < a < 0
    From inequality(2)：
         a < 0 或  a ＞ 0
    From inequality(3)：
         a < 0 或  a ＞ 0
    From inequality(4)：
         a < -1.326352 或  -1.326352 < a < 0 或  a ＞ 0
    From inequality(5)：
         a < 0 或  a ＞ 0

    From inequalities (1) and (2)
         -2.598966 < a < -1.326352 或  -0.635846 < a < 0     (6)
    From inequalities (3) and (6)
         -2.598966 < a < -1.326352 或  -0.635846 < a < 0     (7)
    From inequalities (4) and (7)
         -2.598966 < a < -1.326352 或  -0.635846 < a < 0     (8)
    From inequalities (5) and (8)
         -2.598966 < a < -1.326352 或  -0.635846 < a < 0     (9)

---

    The final solution set is :
         -2.598966 < a < -1.326352 或  -0.635846 < a < 0
