[ 1/1Inequality]
    Assignment:Find the solution set of inequality (-3a-sqrt((3a)^2-4*(-2a)*(a-2)))/(2*(-2a)) <0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( -3 * a - sqrt ( ( 3 * a ) ^ 2 - 4 * ( -2 * a ) * ( a - 2 ) ) ) / ( 2 * ( -2 * a ) ) <0         (1)
        From the definition field of √
         ( 3 * x ) ^ 2 - 4 * ( -2 * x ) * ( x - 2 ) ≥ 0        (2 )
        From the definition field of divisor
         2 * ( -2 * x ) ≠ 0        (3 )

---

    From inequality(1)：
        The solution set is empty, that is, within the range of real numbers, the inequality will never be established!
    From inequality(2)：
         a ≤ 0 或  a ≥ 0.941176
    From inequality(3)：
         a < 0 或  a ＞ 0

---

    The final solution set is :
        The solution set is empty,that is, the inequality will never be estatlished within the real number range.
