Question

Values of k for which the quadratic equation has equal roots is *Values of k for which the quadratic equation has equal roots is
2x^2 - kx + k =0

1. 0 only
2. 4
3. 8 only
4. 0,8​

Answer 1

Answer:

8 only

Step-by-step explanation:

Equal root so :-----

b²-4ac= 0

therefore

k²-4*2k = 0

k² = 8k

k = 8 only

Answer 2

Answer:

it is said by

Step-by-step explanation:

k²- 4*=0 then, it is said find k's value

therefore we know k²=8

so, it is there find k if k²=8 then,

value of k = 4
