I HOPE ITS HELPFUL ☺️

AND PLEASE MARK ME AS BRAINLIST PLEASE

Answer 2

Answer:

Correct option is

D

Both A & B

perfect square = equal roots =Δ=0

∴(2(k+2))

2

−4(4−k)(8k+1)=0

4(k

2

+4+4k)−4(32k+4−8k

2

−k)=0

⇒k

2

+4+4k−32k−4+8k

2

+k=0

⇒9k

2

−27k=0

⇒k

2

−3k=0

⇒k(k−3)=0

⇒k=0 or k=3
