Question

$if \: one \: \: zeroe \: of \: the \: polynomial \: f(x) = 4x {}^{2} - 8kx - 9 \: is \: negative \: of \: the \: other \: find \: the \: value \: of \: k$
​

Answer 1

k = 0

HOPE THIS COULD HELP!!!

Answer 2

Answer :-

→ k = 0 .

Step-by-step explanation :-

It is given that,

→ One zeros of the given polynomial is negative of the other .

Let one zero of the given polynomial be x .

Then, the other zero is -x .

•°• Sum of zeros = x + ( - x ) = 0 .

But, Sum of zeros = -( coefficient of x )/( coefficient of x² ) = - ( -8k )/4 .

==> 2k = 0 .

==> k = 0/2 .

•°• k = 0 .

Hence, it is solved.
