[ 1/1Inequality]
    Assignment:Find the solution set of inequality x/(x^3+2*x^2-4x+3)+6*x^2 <-x .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         x / ( x ^ 3 + 2 * x ^ 2 - 4 * x + 3 ) + 6 * x ^ 2 < - x         (1)
        From the definition field of divisor
         x ^ 3 + 2 * x ^ 2 - 4 * x + 3 ≠ 0        (2 )

---

    From inequality(1)：
         -3.424077 < x < -3.421286
    From inequality(2)：
         x < -3.424077 或  x ＞ -3.424077

---

    From inequalities (1) and (2)
         -3.424077 < x < -3.421286     (3)

---

    The final solution set is :
         -3.424077 < x < -3.421286
