           ☆3 inequalities

[ 1/3Inequality]
    Assignment:Find the solution set of inequality 1/7(p^2-p-2)-p/7-13/7+1 <0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        1 / 7 * ( p ^ 2 - p - 2 ) - p / 7 - 13 / 7 + 1 <0         (1)

---

    From inequality(1)：
         -2 < p < 4

---

    The final solution set is :
         -2 < p < 4
[ 2/3Inequality]
    Assignment:Find the solution set of inequality 1/7(p^2-p-2) >0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        1 / 7 * ( p ^ 2 - p - 2 ) >0         (1)

---

    From inequality(1)：
         p < -1 或  p ＞ 2

---

    The final solution set is :
         p < -1 或  p ＞ 2
[ 3/3Inequality]
    Assignment:Find the solution set of inequality 1/7(p^2-p-2)-2(p/7+13/7)+4 >0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        1 / 7 * ( p ^ 2 - p - 2 ) - 2 * ( p / 7 + 13 / 7 ) + 4 >0         (1)

---

    From inequality(1)：
         p < 0 或  p ＞ 3

---

    The final solution set is :
         p < 0 或  p ＞ 3
