Question

if one zero of the quadratic polynomial 4x sqaure-8kx-9 is negative of the other find the value of k

Answer 1

Hey!

________________

Let @ (alpha) and ß (beta) be the zeroes of the quadratic polynomial 4x^2 - 8kx - 9

Given,

@ = - ß

Then,

@ + ß = 0

- b / a = 0

- (-8kx ) / 4 = 0

8kx / 4 = 0

2k = 0

k = 0
