[ 1/1Inequality]
    Assignment:Find the solution set of inequality n^2+n+4042 >0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         n ^ 2 + n + 4042 >0         (1)

---

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

---

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