[ 1/1Inequality]
    Assignment:Find the solution set of inequality 1/((1-x)^2+1.44*x)^(1/2) >0.9 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        1 / ( ( 1 - x ) ^ 2 + 1.44 * x ) ^ ( 1 / 2 ) >0.9         (1)
        From the definition field of divisor
         ( 1 - x ) ^ 2 + 1.44 * x ≠ 0        (2 )

---

    From inequality(1)：
         -0.279435 < x < 0.839435
    From inequality(2)：
         x ∈ R （R为全体实数），即在实数范围内，不等式恒成立！

---

    From inequalities (1) and (2)
         -0.279435 < x < 0.839435     (3)

---

    The final solution set is :
         -0.279435 < x < 0.839435
