Question

Find the value of K if x-1 is a factor of P(x)=x²+2x+k

Answer 1

Answer:

Hi friend here is your answer.

x-1 is factor of the P(x)=x²+2x+k

So..

x-1=0

X=1

Add the value in equation..

P(1)=1²+2×1+k

0=1+2+k

K=-3

Step-by-step explanation:

Answer 2

Answer:

Step-by-step explanation:

let X= x-1

x=0

so x = x-1=0

    x = 1

remainder=p(1)

p(1)= (1)^2+2(1)+k

    =1+2+k

    =3+k

  k=3
