    Assignment:Find the solution set of inequality 0     Question type: Inequality
    Solution:
    The inequality can be reduced to 2 inequalities：
        0 < x ^ 2 - 0.5 * x         (1)
         x ^ 2 - 0.5 * x <1         (2)

---

    From inequality(1)：
         x < 0 或  x ＞ 1/2
    From inequality(2)：
         -0.780776 < x < 1.280776

---

    From inequalities (1) and (2)
         -0.780776 < x < 0 或  1/2 < x < 1.280776     (3)

---

    The final solution set is :
         -0.780776 < x < 0 或  1/2 < x < 1.280776
