Let alpha, beta be roots of the equation x^2-x-1 = 0 and An=alpha^n +beta^n, n in I, then A(n+2)+ A(n-2) is equal to-
with A and B being two roots of some quadratic equation z2=αz−β. Then from the nature of equations it will be A+B=α,AB=β But for defining α and β from a and b, I take the equation x=A3+B3, which multiplied as a cube gives x3=A+B+3AB3(A3+B3)=3xAB3+A+B....
