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

---

    From inequality(1)：
         -5 ≤ x ≤ 2
    From inequality(2)：
         x < 1 或  1 < x < 2 或  x ＞ 2

---

    From inequalities (1) and (2)
         -5 ≤ x < 1 或  1 < x < 2     (3)

---

    The final solution set is :
         -5 ≤ x < 1 或  1 < x < 2
