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, factories f(x) completely​

Answer 1

Answer:

Step-by-step explanation:

factor | f(x) = x^3 + 2 a x + b

Factor[f[x] == x^3 + 2 a x + b]

f(x) = 2 a x + b + x^3

f[x] == b + 2 a x + x^3
