Question

if one zero of the quadratic polynomial f(x)=4x^2-8kx+8x-9 is negative of the other ,then find the zeros of kx^2+3kx+2.

Answer 1

See the attachment for the answer.

So, the other polynomial is given by

x^2 + 3x + 2

= (x + 2)(x + 1)

So, the zeroes are (-2) and (-1).

Thank you for your question.

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.
