[ 1/1Inequality]
    Assignment:Find the solution set of inequality x+1 ≥0.8*sqrt(x+2) .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         x + 1 ≥0.8 * sqrt ( x + 2 )         (1)
        From the definition field of √
         x + 2 ≥ 0        (2 )

---

    From inequality(1)：
         x ≥ 0.181626
    From inequality(2)：
         x ≥ -2

---

    From inequalities (1) and (2)
         x ≥ 0.181626    (3)

---

    The final solution set is :
         x ≥ 0.181626
