Question

Find the value of k in quadratic equation 2x^2-kx+k=0 has equal roots

Answer 1

hey! hope it helps you out

Answer 2

Answer:- k=8

Step-by-step explanation:-

Given equation is 2x2 – kx + k- 0

On comparing with ax2 + bx + c = 0, we get

a = 2, b= – k and c = k

For equal roots, the discriminant must be zero.

So by quadratic formula we can calculate this....

Hence, the required values of k are 0 and 8.
