_______________________________

For equal roots Descrimnant =0

=>

Descrimnant = 4( 1+ 3k )² - 4 ×7 ( 3+2k )

=>

1² + 9k² + 6k -21 - 14k = 0

=>

9k² - 8k - 20 = 0

=>

k = 8 +- √(64+720) /18

=>

k = (8 +- 28) /18

=>

k = 36/18 OR k = -20/18

=>

k = 2. OR. k = -10/9

Answer 2

K=2...................
