Let u=x+2. After simplifications, we'll get u^6+90u^4+810u^2=0, and then u^2(u^4+90u^2+810)=0. So, u^2=0 gives x=-2 and we have to solve u^4+90u^2+810=0. We get negative values for u^2, so no other real solutions. The only real solution is x=-2.

Let U=(X+2)/3, U-1=(X-1)/3, U+1=(X+5)/3, (U-1)^6+U^6+(U+1)^6=2

2*3^6 could be simplified at a point did not understand why u didn’t
