What did you do

itsav23OP•9/9/24, 12:58 PM

Used the condition for a pair of straight lines(D=0) and after substitution got the equation. But uske baad I am not sure what to do next.

then check the inequalities

Slembash•9/9/24, 2:04 PM

h^2 >= ab , g^2 >=ac ,, f^2>=bc

Slembash•9/9/24, 2:04 PM

i think solving any 1 ineuality gives u the answer, but for now check all 3, to know if it makes a difference or not

Slembash•9/9/24, 2:22 PM

well this inequality works ezily if no.s were thr, but with variables even i m confused how to proceed

itsav23OP•9/9/24, 3:25 PM

nope do inequalities would be a>= p and a>=q but ans is (-

,p] U [q,

)

Slembash•9/9/24, 3:45 PM

well this answer comes if u put condition on D of the quadratic formed after solving D of straight lines

itsav23OP•9/9/24, 5:04 PM

yep...solved it. Thanks
