1. The problem statement, all variables and given/known data The problem is If x= 2+2 2/3 +2 1/3 solve x 3-6x 2+ 6x-2 =0 2. Relevant equations 3. The attempt at a solution First i tried to substitute the values but its turning out to be really big( and i get quite scared when it turns up like this and so i didn't go any further this way) then I tried to make a cube of x-1 Like this x3 -1 -3x 2+ 3x-3x 2+3x-1+x 3=0 <==>(x-1)3+(x-1)3=x 3 <==>2(x-1)3=x 3 Well I can't get any further!! Happy if anyone helps!!
