      i dont know if u will read this or not but here your answer
      x2=6x+2
      alpha2=6alpha+2———1
      multiply eq1 by alpha^8
      alpha^10=6alpha^9+2alpha^8
      do the same with bheta and name the eq 2 and then subtract eq 2 from 1
      you will get
      alpha10-bheta10=alpha9-bheta9+alpha8-bheta8
      which will be equal an=alpha^n-bheta^n
      a10=6a9+2a8
      a10-2a8=6a9
      a10-2a8/2a9=3

      you welcome

    Alright . Why we didn’t consider 3 in 8 question although it’s satisfying the equation? Any one pls

      Well, 3 is a solution for x^2 – 5x + 5 = -1, right so the quadratic is power that is X^2 + 4x – 60 should be even as (-1)^even number = 1 and (-1)^odd number = -1. Putting x = 3 in X^2 + 4x – 60 gives and odd number. Hence 3 is rejected.
