Answer:
ok I got your question the answer is k = 0 and 1/4
Step-by-step explanation:
in order for the equation to have equal roots the D or discriminant should be equal to zero
therefore b^2 -4ac should be equal to 0
putting the values in:
16k^2 -4k=0
4k^2-k = 0 (taking 4 as common and transporting to r.h.s)
k(4k-1) = 0 (k as common)
therefore k is either 0 or 1/4
hope this answer helped have a great day!!
