Question

) Find the value of k if x - 1 is a factor of p(x) = x2 + x +k​

Answer 1

Answer:

k= -3

Step-by-step explanation:

if x-1,. then x=1

and putting x=1 in x2+x+k

2×1+1+k=0

3+k=0

k=. -3

Answer 2

We know that if "x-1" is a factor then, 0 of "x-1" will make the equation 0.

So, x-1 = 0

      x = 1

(Now substitute the value of x in the equation.)

0 = 1 (2) + 1 + k

0 = 3 + k

-3 = k

Hence the value of K must be "-3"
