Question

5. If the equation 9x + 6kx +4 -0 has equal roots then the roots are both equal to
(a) = 2 / (b) + 2 (c) (d) + 3​

Answer 1

Answer:

D is the correct

Step-by-step explanation:

Answer 2

Answer:

D= b2-4ac = 0 (if the equation has equal roots)

6k power of 2 - 4.9.4 =0

36k^2-144=0

k^2=144/36

k=12/6

k=2
