![{x}^{2} + (k - 1)x - k = 0](https://tex.z-dn.net/?f=%20%7Bx%7D%5E%7B2%7D%20%20%2B%20%28k%20-%201%29x%20-%20k%20%20%3D%200)
![(x - 1)(x + k) = 0 \\ x = 1 \\ x = - k](https://tex.z-dn.net/?f=%28x%20-%201%29%28x%20%2B%20k%29%20%3D%200%20%5C%5C%20x%20%3D%201%20%5C%5C%20x%20%3D%20%20-%20k)
they are equal so both are one
then k = -1
