    Assignment:Find the solution set of inequality -2m*m-m+1     Question type: Inequality
    Solution:
    The inequality can be reduced to 2 inequalities：
        -2 * m * m - m + 1 < m * m - 3         (1)
         m * m - 3 <2 * m * m + m - 1         (2)

---

    From inequality(1)：
         m < -4/3 或  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)
         m < -4/3 或  m ＞ 1    (3)

---

    The final solution set is :
         m < -4/3 或  m ＞ 1
