    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!!
