Question

9. Find the values of a and b so that X raise to 4
+ x^3 + 8x^2+ax+b divisible by x2+1​

Answer 1

Answer:

Now, if x4+x3+8x2+ax+b is divisible by x2+1 , then the remainder should be equal to zero. Thus, we find that the values of a and b so that x4+x3+8x2+ax+b becomes divisible by x2+1 is a=1 and b=7 which is the required answer to the given question
