No real solutions if k is greater than 3 as an integer because the value of the discriminant of b^2 -4ac will be less than 0.

No real solutions will occur when the discriminant is less than 0.

b^2 - 4ac < 0

(8)^2 - 4(k)(5) < 0

64 - 20k < 0

-20k < -64

20k > 64

k > 64/20

k > 32/10

k > 16/5 <== answer
