Coolest thing I have ever seen about maths and algebra

[chiragdhindhwal]

It is a identity in itself
If x +1/x=a
Then
X2+1/x2=a2-2

[juneidfarwad]

But what I do if it is '-' sign.

Byjus is known for its concept visualisation, don't be like other platform which just just focus on mugging and tricks without knowing actual reason behind that.

A humble request for students and teachers, please explain the concept to a child clearly and don't make them mug up these kind of tricks or they're gonna end up having problems in higher secondary levels
