If one zero of quadratic polynomial 4x²-8kx-9 os negative of the other find the value of k

Answer»

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 .

\therefore k = 0 .

Hence, it is SOLVED.
