X2n (xn + x-n)2 – (1 + x4n)

__(-1)__n__+ (-1)__n+2

2(-1)n + (-1)n+1 - Aug 1st 2008, 11:03 PM11rdc11
Is it

1) x2n(xn+(-nx))2 -(1 +x4n) or 2) 2xn(xn + n - x)2 -(1 + 4xn)

either way i provide answers for both

1) 2xn(0)2 -(1+4xn)

-(1+ 4xn)

2) {(2x^2n^2) +(2xn^2) -(2x^2n)}2 -(1 + 4xn)

(4x^2n^2) + (4xn^2) -(4x^2n) - 1 + 4xn

Hope that helps
