And would it be too much if I ask you to explain it step by step ? Pleeeeaaaase =P

Please, would you do it and let me know if you got the answer given ? Coz I took the 3 intervals, but I do not know how to use the restriction |x+2|-|x-1|>=0 on the final results.

How can I solve, step by step, this inequality ? The result I have is [ 1 , (-1 + sqrt33)/2 ] but the result should be [ 0 , (-1 + sqrt33)/2 ]|x+2|-|x-1|\geq\sqrt{x^2+x+1} thanks for ur help =)
