The value of

k(k>0)

for which the equations

x^2+k x+64=0

and

x^2-8 x+k=0

, both will have real roots is

View answer and explanation

Correct option: A

Option A (16) is correct because for both quadratic equations to have real roots, their discriminants must be non-negative, leading to

k=16

as the only positive solution that satisfies both conditions.
