Question

if one zero of 4x² - 9 - 8kx is negative of the other find the other zero ​

Answer 1

Answer:

Let two roots of quadratic equation are x(1) & x(2).

Then according to question,

x(1) = -x(2)

x(1) + x(2) = 0

-(b/a)=0 ( sum of roots = -(coefficient of x / coefficient of x^2) )

8k/4=0

k=0
