Question

If one zero of 4x²-9-8kx is negative of the other find k.

Answer 1

Hello user☺☺

Since, the zeroes of 4x²-9-8kx are negative of each other.

So, lets assume one of them to be x
then, other will be -x

Now, using the zeroes-coefficient relation, we have

x-x = -(-8k)/4

8k/4 = 0

k = 0.

Hope this will help☺☺

Answer 2

Step-by-step explanation:

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.
