    Assignment:Find the solution set of inequality （-2x-sqrt(4x^2-12))^2+x*（-2x-sqrt(4x^2-12))+1 >0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( -2 * x - sqrt ( 4 * x ^ 2 - 12 ) ) ^ 2 + x * ( -2 * x - sqrt ( 4 * x ^ 2 - 12 ) ) + 1 >0         (1)
        From the definition field of √
         4 * x ^ 2 - 12 ≥ 0        (2 )
        From the definition field of √
         4 * x ^ 2 - 12 ≥ 0        (3 )

    From inequality(1)：
         x ＞ -2.245366
    From inequality(2)：
         x ≤ -√3 或  x ≥ √3
    From inequality(3)：
         x ≤ -√3 或  x ≥ √3

---

    From inequalities (1) and (2)
         -2.245366 < x ≤ -√3 或  x ≥ √3    (4)
    From inequalities (3) and (4)
         -2.245366 < x ≤ -√3 或  x ≥ √3    (5)

---

    The final solution set is :
         -2.245366 < x ≤ -√3 或  x ≥ √3
