Given,
x^2+x=1
x=1-x^2
Now,Putting the value of x in another Equation we get,
((1-x^2)+2)^3+1/((1-x^2)+2)^3
=(1-x^2)^3 +3*(1-x^2)*2 + (2)^3 + 1/ (1-x^2)^3 +3*(1-x^2)*2 + (2)^3
=1+1
=2
x^2+x=1
x=1-x^2
Now,Putting the value of x in another Equation we get,
((1-x^2)+2)^3+1/((1-x^2)+2)^3
=(1-x^2)^3 +3*(1-x^2)*2 + (2)^3 + 1/ (1-x^2)^3 +3*(1-x^2)*2 + (2)^3
=1+1
=2
