Answer:
k must be less than 16.
Step-by-step explanation:
For the equation to have 2 distinct real roots the discriminant (b^2 - 4ac) must be greater than 0 zero.
So we have the inequality 8^2 - 4*1*k > 0.
Note if k is equal to 16 it will have duplicate roots ( both equal to 4).
4k < 64
k < 16 (answer).
