(a) 2,4
(c) 1-4
(b) -1,4
(d) उपरोक्त में से कोई नहीं / None of the above​

Answer 1

Answer:

value of p is 1/2 and -1/4

so option d is correct.

hope you got your answer

Answer 2

8p²-2p-1=0

solution is (1/2,-1/4)

= 8p²-2p-1=0. { 8 = (-4) x (+2) }

= 8p²-4p+2p-1=0

= 4p(2p-1)+1(2p-1)=0

= (2p-1)(4p+1)=0

= 2p-1=0 or 4p+1=0

= 2p=1 or 4p=-1

= p=1/2 or p= -1/4

= p = (1/2,-1/4)

THE OPTIONS GIVEN BY YOU ARE INCORRECT

I hope that you are comfortable with this answer.
