1st of all x cannot be negative as all the terms become +ve.
Morover, x cannot be <1 (obvious, isn't it?)
So, x≥1
Now, The inequality x2-x+2≤0 is satisfied for 1≤x≤2
So, the given inequality will be satisfied for a subset of [1,2]
It is apparent that for x≥√2 the given inequality is not satisfied.
So x ε [1,√2)

The soln given for this question is absolutely wrong.
soln is x ε [1,√2).

the correct solution is [1,√3)
