I have no idea what this might mean: "...roots include x=1-(2) and x=2+(5)"
--------------------------------------------------
(The student said it was supposed to mean 1-sqrt(2) and 2+sqrt(5)...)
To the student:
Re-post the question making that clear. Just sending me a message doesn't make the problem visible to the other tutors.
