Question

if one zero of the polynomial 4x2-9-8kx is negative of the other, find the value of k.

myself disha from my house​

Answer 1

Answer:

Given: 4x²-8 kx - 9

Let the zeroes be a and 3

ATQ

a = -3

⇒a+B=0

coefficient of x coefficient of ² Sum of zeroes

a + B =

0=

-(-8k)

4

-(-8k)

4

⇒k=0

Explanation:

ok

thank you

Answer 2

Explanation:

hence

Hence, the value of k is 0.

i hope its help u
