Maths ke doubts

-So pehli cheez Hai ki uss shreedaracharya formula (quadratic eqn) mein case 1 case 2 likhna zaroori Hai kya? Meri tuition teacher boli ki chalta Hai agar nahi likha

-Linear inequations ke number line mein do you have to like color the circle like on the spot where it is or can it be like elevated thoda sa above the number line balloon jaise? Our teacher said ki you can do it either way but tuition teacher said do it how it is in book (on the spot) bcuz that's what board wants or whatever

-Log book milega kya board exam mein?? Our teacher again said ki they give log book for values of roots or a paper w/ values of roots but tuition teacher said they don't give in boards aur uske saath bhi boli ki "your teacher has gone mad" like wtf is up w/ that

Sorry for the yapping and ik maths exam is over par 😭 madat karo pls darr lag rha hai
