Question

the value of k for which the equation 9x²+8kx+1​

Answer 1

Answer:

the value of k will be idk

Answer 2

on comparing this eq with standard form of quadratic equation ax²+bx +c =0

we get

a= 9 , b= 8k and c= 1

for real and equal roots

D=0

b²-4ac =0

(8k)²-4×9 =0

64k²-36 =0

k²= 36/64

k= 6/8

k= 3/4
