- For a positive integer n, le Pn(r) = (x + 1)(r+2) (x + n). Show that the set of polynomials Pn (x) Pn(r) I+1'r+2 Pn(x) I+n] is linearly independent for any n. For example, the set for n = 3 is {(r + 2)(r + 3), (x + 1)(x + 3), (x + 1)(x + 2)}. (Hint: Set up a linear independence argument and try evaluating for r at certain values.)

i would like help with question 5

- For a positive integer n, le Pn(r) = (x + 1)(r+2) (x + n). Show that the set of
polynomials
Pn (x) Pn(r)
I+1'r+2
Pn(x)
I+n]
is linearly independent for any n.
For example, the set for n = 3 is {(r + 2)(r + 3), (x + 1)(x + 3), (x + 1)(x + 2)}.
(Hint: Set up a linear independence argument and try evaluating for r at certain
values.)
