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

---

    From inequality(1)：
         x ＞ 1
    From inequality(2)：
         x ∈ R (R is all real numbers),that is, in the real number range, the inequality is always established!
    From inequality(3)：
         x ∈ R (R is all real numbers),that is, in the real number range, the inequality is always established!

---

    From inequalities (1) and (2)
         x ＞ 1    (4)
    From inequalities (3) and (4)
         x ＞ 1    (5)

---

    The final solution set is :
         x ＞ 1
