@waterineyes Plz tell the question in HINDI :)

anonymous · Answer

Okay...

Yeh question (prachhan) keh raha hai ke agar is equation ke roots ka difference 2 hai to "k" ki value pata lagaayein...

Logically,
Quadratic equation ke do roots hote hain,
to unka difference hamein given hai as 2,
agar main ek root ko a maanta hu aur dusre ko b to:

a - b = 2   (Given)

Getting?
Samajh aa raha hai tumko Viper??

aage kya hoga @waterineyes ??

anonymous · Answer

Tumko pta hai agar hamaare paas standard equation hai:
$$ax^2 + bx + c = 0$$

To tumko pta hai ke Sum of roots ka formula kya hota hai??

Aur product of roots ka kya hota hai??

theviper · Answer

Sum of roots=-B/A
Product of roots=C/A

anonymous · Answer

Yes....

Ab jo hamein equation given hai uske liye sum of roots aur product of roots nikaalo..

Pehle (x-1)(x-5) ko multiply kar lena..
