Question

if one of the zeroes of the quadratic polynomial f(X) = 4 X square - 8 kx-9 is equal to magnitude but opposite in sign of the other, then find the value of k​

Answer 1

Answer:

K=0

Step-by-step explanation:

Let the zeroes are A and B

A=(-B)  ______equation 1

Sum of zeroes = -b/a

A+B=[-(-8k)/4]

A+(-A)=8k/4_____________by 1st equation

0=2k

k=o
