Question

If x +1 and x -1 are factors of f(x) = x³ +2 ax +b, calculate the values of a and b. Using these values of a and b, factorise f(x) completely. ​

Answer 1

Step-by-step explanation:

I would have helped you but I'm sorry i don't know the answer.

Answer 2

(x+1)(x-1)is a factor of f(x)

using factor theorem,we get two different equation

hope it helps
