Use factor theorem to prove that (x+a)b is a factor (xn+an) for any odd positive integer n Let f(x) =xn+an n is odd positive integer  Let take (x+a)=0 x=-a Let  us consides f(x) =xn+an put x=-a f(-a)=(-a)n+an =-an+an =0 Since n is  odd By factor theorem Hence proved that (x+a) is a factor of f(x) where n is odd  positive integer
