Question

If one zero a polynomial as 4x squre-8kx+8x-9 is negarive of other then find zero of kx squre +3kx+2

Answer 1

Let one zero pf quadratic polynomial be x

other zeroes =-x

Sum of zeroes=-b/a

x-x= 8k by 4

0=8k by 4

K=0

I hope my answer wil help u

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.
