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

---

    From inequality(1)：
         -1.001994 < x < 4.261433
    From inequality(2)：
        The solution set is empty, that is, within the range of real numbers, the inequality will never be established!

---

    The final solution set is :
        The solution set is empty,that is, the inequality will never be estatlished within the real number range.
