Question

if one zero of the quadratic f(x)4x^2 -8kx - 9

polynomial
is negative of the Other find the value of k

Answer 1

k=0
let one zero be a
then other zero wil be -a
a+(-a)=-(-8k)/4
which implies k=0

Answer 2

here is your answer by Sujeet,

Let to be a other zeroes of this quardratic polynomial,

Then,
a/q
Negative zeroes=-a

a+(-a)=-b/a
a-a=-(-8)kx/4x
0=-2k
2k=0
k=0/2
k=0





that's all
