If (x100 + 2x99 + k) is divisible by (x + 1), then the value of k is
Let p (x) = x100 + 2x99 + k
It is given in the question that, (x + 1) is divisible by (x + 1)
So, p (-1) = 0
(-1)100 + 2 (-1)99 + k = 0
1 + 2 (-1) + k = 0
1 – 2 + k = 0
- 1 + k = 0
k = 1
Thus, the value of k = 1
Hence, option A is correct
