Vernier calipers

[~Sakura~]

Main o level kar rahi hoon aur physics main mujhe aik cheez samajh nahin a rahi............
Vernier calipers main reading kis tarha hoti hai...............?
Book main sahi tarha se explain nahi kia gaya aur uske ilawa mujhe yeh bhi poochna tha ke quadratic formula kia hai (yani kis tarha use hota hai etc etc)
Hope anyone can help

Quadratic Equation ke mutaliq inshort batata chalun
Jo equation is form me ho
ax² + bx + c
or ye ap se factorize na horaha ho to ap quadratic formula use kartey hain takey equation ke factors maloom hosake ke bani kese he.
for example
x² + 3x – 4
ye equation he yahan quadratic formula lagane ki zarorat nahi he ye isi tarah parts me divide hojata he jese
(x + 4)(x – 1) = 0
x=-4 and x=1

laikin bilfarz aise equation ho
2x² – 4x – 3
to ye phir quadratic formula use karne se solve honge
a=2 b=-4 and c=-3
