Question

Solve for x :
[x]^3 - 2[x] + 1 = 0
([.] is the greatest integer function)

Answer 1

let [x]=t
so t comes out to be 1 and some other 2 roots
[x]=1 so 1<x<2
:)

Answer 2

@Aperogalics - x can also take '1' :)

Answer 3

ya i just type it but think it is not typed ;)

Answer 4

its cubic equation bro, not quadratic

Answer 5

Yes by trial [x]= 1 is solution.
Diving the poly by [x]-1(factor), we get : \[[x]^{2} + [x] - 1\]
which doesnt have any integral solution
Hence the solution of the poly is : 1\[\le x < 2\]
