Question

Find the value(s) of k so that the quadratic equation x2 - 4kx + k = 0 has equal roots.​

Answer 1

Answer:

Step-by-step explanation

According to the given condition

b^2-4ac=0

(4k)^2-4(1)(k)=0

16k^2-4k=0

16k^2=4k

k^2=k/4

k=root k/2

Answer 2

Answer:

1/4

Step-by-step explanation:

for equal root,

b^2-4ac=0

4k^2-4×1×k=0

16 k^2=4k

k= 1/4
