Re: Maths help available here!!! Stuck somewhere?? Ask here!

A simple question, guys

If m^2>16

then the answer to this inequality is:

m>4 or m<-4

why is that
could you please explain that
does it mean that when the negative square root of a number is taken, the inequality sign changes?

I typed the Quadratics notes and only little bit of it was left, and i dont know what happened, there was a problem and microsoft word closed :cry: and now all what i typed is lost :cry:

I dont even have time, and then what I did , I dont want to do it again :cry:

Ofcourse, there must be something better than this what Allah has for me...I put my trust in him, and apologize that I couldn't upload the notes!
