Question

6. The polynomial f(x)=x^4 - 2x^3 +3x^2 - ax + b when divided by (x - 1) and (x + 1) leaves the
remainders 5 and 19 respectively. Find the values of a and b. Hence, find the remainder when
f(x) is divided by (x - 2).​

Answer 1

Step-by-step explanation:

let x be 5 first and substitute in p(x)

look at the above image

let x be 19 then substitute in p (x)

now see how I have substituted in the above case
