Question

If 1 is one of the zeroes of the polynomial x ^2 + x + k , then the value of k is :​

Answer 1

Answer:

k = -2

Step-by-step explanation:

x = 1

(1)^2 + 1 + k = 0

k = -2

Answer 2

Answer:

k = -2

Step-by-step explanation:

p(x) => x^2  +  x  +  k  =  0

p(1) =>  1^2  +  1  +  k  =  0

      =>  2  +  k  =  0

      =>  k  =  -2
