Question

find the value of k,if x-1is a factor of x2 +x+k​

Answer 1

Answer:

Step-by-step explanation:

x-1=0

x=1

x²+x+k=0

2+k=0

k=-2

Answer 2

Answer:

k=(-2)

Step-by-step explanation:

According to the reminder theorem:-

If x-1 is a factor then p(1)=0

so, p(1)=>(1)²+1+k=0

=>2+k=0

=> k=(-2)
