Answer:

Step-by-step explanation:

The roots are equal therefore  b²- 4ac = 0

Substitute values of a, b and c.

( -4k )² - 4 x 3k x ( 4 ) = 0

16k² - 48k = 0

16k ( k- 3) = 0

16k = 0       or     k - 3 = 0

k = 0          or     k = 3

but k cannot be zero as 'a' term of quadratic equation is never zero.

Therefore k = 3
