pls.answer quikly .... really urgent

Let f (x) be a polynomial of degree greater than one. If f (x) is divided by x - a then f (a) is

remainder.

7. Let f (x) = x²⁰¹³ +1 then the remainder when f (x) is divided by x2 -1 is

(A) x -1 (B) x + 1

(C) 0 (D) 1

8. If f x  x3  px  q is divisible by x2  x  2 then p.q 

(A) 2 (B) 4

(C) 6 (D) 8

9. f(x) be a polynomial such that f (a) = f (b) = f (c) = f (d) = 3. Where a, b, c, d are distinct

integers. If f(e) = 5, where e is an integer than e =

(A) 1 (B) 3

(C) 4 (D) no real value of e is possible
