Question

the value of K for which the equation 9x^2+8kx+8=0 has equal roots solve this equation of quadratic equation of 10th class ​

Answer 1

Step-by-step explanation:

For equal roots

discriminant must be equal to zero

D = b²-4ac must be zero

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

so (8k)²-4×9×8= 0

64k²= 288

k² = 9/2

k = 3/√2

k = 2.1

4.3

Answer 2

Answer:

the value of K for which the equation 9x^2+8kx+8=0 has equal roots solve this equation of quadratic equation of 10th class
