Dear manan

earlier i have replied to this problem ,at that time u have not maintion the complex root so i was only dealing real roots.

for complex root you have to solve it




you can factorise it easly with the formula

 a3 + b3 = (a+b)(a+bw)(a+bw2)    where w is the cube root of unity

 {(x-1)+2}{(x-1) +2w}{(x-1) +2w2} =0

 ( x+1)(x +2w-1)(x +2w2 -1) =0

  it gives the root  1,1-2w,1-2w^2
