Answer:

k = 8

Step-by-step explanation:

If they have real roots, then discriminant D will also be equal to zero.

 \bold{ {b}^{2}  - 4ac = 0}

 \bold{ {(8 \sqrt{2}) }^{2}  - 4 \times k \times 4 = 0}

 \bold{128 - 16k = 0}

 \bold{ - 16k =  - 128}

 \bold{k =  \frac{ - 128}{ - 16} }

 \bold{ \boxed{ \bold{k = 8}}}

Hence the value of K is 8
