Answer 2

a)  = x^2 (x + 1) + (x + 1)  =

         (x + 1) (x^2 + 1)

c) = x^4 (x^2 - 1) - 16 (x^2 - 1) =

      (x^2 - 1) (x^4 - 16) =

      (x - 1)(x + 1)(x^2 - 4) (x^2 + 4) =

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

e) = x^2 ( x + 1) - 25 (x + 1) =

      (x + 1)(x^2 - 25) =

      (x + 1)(x + 5)(x - 5)

h) = x^2 ( x + 4) - 16( x + 4) =

       (x + 4)(x^2 - 16) =

       (x + 4)(x - 4)(x + 4)

g) = x^3 (x - 9) - (x - 9) =

       (x - 9) (x^3 - 1) =

       (√x + 3)(√x - 3) (x - 1)(x^2 + x + 1)
