Question

The values of k for which the quadratic equation 16x^2+4kx+9=0 has real and equal roots are

Answer 1

SOLUTION

TO FIND VALUE OF K

GIVEN

equation 16x^2 + 4kx + 9 = 0 has real and

equal roots

For real and equal roots:-

D = b^2 - 4ac = 0

(4k) ^2 - 4 (16) (9) = 0

16k^2 - 576 = 0

k^2 = 576/16

k = √576/16

k = 24/4

k = 6 = ANSWER
