Question 972931
 x³-6x²+6x.  Initially, this was not clear that they were exponents.


****************************
I subsequently learned that x=2+2^(2/3) +2 (1/3)
                                              2+2^(2/3) +2 (1/3)

To factor this out completely is extremely difficult.  It is easier to add the 3 terms, and to four decimal places it is 4.8474

4.8474^3-6[4.8474^2]+6(4.8474)=2.0014
