[ 1/1Inequality]
    Assignment:Find the solution set of inequality sqrt(2m^2+6m+5) <1 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         sqrt ( 2 * m ^ 2 + 6 * m + 5 ) <1         (1)
        From the definition field of √
         2 * x ^ 2 + 6 * x + 5 ≥ 0        (2 )

---

    From inequality(1)：
         -2 < m < -1
    From inequality(2)：
         m ∈ R (R is all real numbers),that is, in the real number range, the inequality is always established!

---

    From inequalities (1) and (2)
         -2 < m < -1     (3)

---

    The final solution set is :
         -2 < m < -1
