Find the correct answer friends

Answer 1

______________________________

let a and b be roots of equation

so let a = x , b= 1/x (given)

given equation :

=) lx^2 +mx +n = 0

so , product of roots : ab = 1

and ab = n/l

now equating both values we get .

=====) n/l = 1

=). ◆ n = l : it's the required condition...
