[ 1/1Inequality]
    Assignment:Find the solution set of inequality X-1/X+2-3 ≤0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         X - 1 / X + 2 - 3 ≤0         (1)
        From the definition field of divisor
        x ≠ 0        (2 )

---

    From inequality(1)：
         X ≤ -0.618034 或  0 ≤ X ≤ 1.618034
    From inequality(2)：
         X < 0 或  X ＞ 0

---

    From inequalities (1) and (2)
         X ≤ -0.618034 或  0 < X ≤ 1.618034     (3)

---

    The final solution set is :
         X ≤ -0.618034 或  0 < X ≤ 1.618034
