Wahi tarika hai I tried kahi phas raha hu
Bro iss chapter ke liye conic sections krna pdega?
Revise
No you can actually derive formule by this chapter you just need to know general equations of all the conic sections
True.
Also aod is just questions.
We can put h1 back to get the eq of line, it's lengthy and required elimination of multiple variables
Now the other two roots of the this equation are non real (can be seen by long division method?

Actually, they just applied $c^{2}=a^{2}m^{2}+b^{2}$ I think (condition for tangency).
