[ 1/1Inequality]
    Assignment:Find the solution set of inequality （2z^3+9z^2+z）/6 ≥-6^z .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( 2 * z ^ 3 + 9 * z ^ 2 + z ) / 6 ≥ -6 ^ z         (1)

---

    From inequality(1)：
         z ∈ R (R is all real numbers),that is, in the real number range, the inequality is always established!

---

    The final solution set is :
         z ∈ R (R is all real numbers),that is, in the real number range, the inequality is always established!
