Question

Find the value of k if x -1 is a factor of x2+X+k?

Answer 1

Answer:

-2

Step-by-step explanation:

since x-1 is a factor of the given polynomial,

p(x)=1

therefore,

1^2 + 1 +k = 0

2+k=0

k=-2

Answer 2

Answer:

Step-by-step explanation:

x - 1 is a factor of x^2 + x + k means that 1 + 1 + k = 0 which means that

k = - 2.
