The two equations can be written as
x
2
(6k+2) + rx +(3k-1) = 0 ...(1)
and x
2
{12k + 4) + px + (6k - 2) = 0. ...(2)
Divide by 2
∴ x
2
(6k+2)+
2
p
x + {3k-1)=0 ...(3)
Comparing (1) and (3), we get r =
2
p
∴ 2r-p = 0.

Answer:

and x
2
{12k + 4) + px + (6k - 2) = 0. ...(2)
Divide by 2
∴ x/2
(6k+2)+ 2p
x + {3k-1)=0 ...(3)
Comparing (1) and (3), we get r = 2p
∴ 2r-p = 0.
hope it helps you. plz mark me as the brainiest..
