Question

My question is class9 and ncrt book ex 2.4​

Answer 1

Answer:

k=-2

Step-by-step explanation:

Since x-1 is a factor, when we divide p(x) with x-1, the remainder is zero.

So,

${x}^{2} + x + k = (x - 1)(x + 2) + (k + 2)$

The remainder is

$k + 2$

But, remainder must be zero.

So

$k + 2 = 0 \\ k = - 2$

Hence, k=-2 is the required answer.

Thank you
