- its 6 ans

- root 1=p+sqrt(p^2-32)/2
root 2=p-sqrt(p^2-32)/2
root 3=-p+sqrt(p^2-32)/2
root 4=-p+sqrt(p^2-32)/2
now acc to ques
root1-root2=6 and similarly
root3-root4=6
hence 6 is verfied

- d)-6 by simple equation
- 11 years agoHelpfull: Yes(2) No(5)
- the answer should be 6.

- (-p +root(p2-32))/2 =(p+root(p2-32))/2 -12; by sol this p=6

- -6 is the ans
- 11 years agoHelpfull: Yes(0) No(7)
- its -6 cz 6x2-(-6)x+8=0
- 11 years agoHelpfull: Yes(0) No(2)
- 6 & -6, both are satisfying the conditions
