Question

pls. solve this qn. urgently..

no spams pls..​

Answer 1

Answer:

Let one zero be a then the other will be 1/a from the above step we can see that the product of the roots is 1 so c/a=1

4k/k^2+4=1

4k=k^2+4

k^2-4k+4=0

(k-2)(k-2)

hence k=2

Answer 2

Answer:

Let one zero be x.

Reciprocal=1/x

We know,

Alpha**beta=c/a

x*1/x=4k/k²+4

K²+4=4k

K²-4k=-4

k^2-4k+4=0

(k-2)(k-2)

hence k=2
