Step-by-step explanation:
let us consider one zero of the polynomial = a
according to the ques
other zero polynomial = -a
sum of roots = a + (-a) = 0
we know that,
for a quadratic equation,
sum of roots = -( coefficient of x ) / coefficient of x^2
given polynomial = x^2 + 4kx -25
so, sum of roots = 4k/1 = 4k
sum of roots = 0
k = 0/4 = 0
