# If -4 is a root of the equation x2 +px -4=0 and the equation 2x2 +px +k=0 has equal roots find 'k'If -4 is a root of the equation x2 +px -4=0 and the equation 2x2 +px +k=0 has equal roots find 'k'

=> x = 14

=> -4 x -4 + p x -4 -4 = 0

=> 16 - 4p - 4 = 0

=> -4p = -12

=> p = 3

Now, second eqn has equal roots

=> b2 - 4ac = 0

=> p2 - 8k = 0

=> -8k = -9

=> k = 9/8

I am not sure about the calculation, so plz check it out again, otherwise the procedure is correct :D
