Is this inequation correct?

Is this step of this inequation is correct,I got it from a book and I guess its wrong or may be I am missing something

How come the sign changed? To me it doesnt make any sence.

Hi debjit625;

Looks like a typo.

In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
No great discovery was ever made without a bold guess.

It's wrong. The sign should've stayed the same...
