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.  pls tell me as early as possible​

Answer 1

Answer:

hey mate,

here your answer

Explanation:

Mark me brilliant and thanks

Answer 2

Answer:

f(x) = x³+2ax+b

g(x) = x+1

g(x) = 0

x+1=0

f(−1)=0

In second case,

f(x) = x³+2ax+b

g(x) = x-1

g(x) = 0

x-1=0

x=1
