Question

When f(x) = x3 + ax2 + bx + 2 is divided by (x – 1), it leaves a remainder of 5 and when divided by (x + 1) the remainder is 13. Using remainder theorem, find the values of a and b in f(x).

Answer 1

Step-by-step explanation:

f(x)=x³+ax²+bx++2

f(1)=5 , f(-1)=13

1+a+b+2=5

a+b=2 equation 1

f(-1)=13

-1+a-b+2=13

a-b=12 equation 2

solving equation 1 and 2

a=7 b= -5

Answer 2

Answer:

that is a correct answer
