There are many questions i can't get. This is just one. Can anyone give me a hint on what to do? It's probably really simple :((adsbygoogle = window.adsbygoogle || []).push({});

If A and B are real numbers such that [tex]|A - B| < \frac{1}{2}[/tex], show that:

[tex]|A^2 - B^2| \leq \frac{1}{2} \{2|B|+

\frac{1}{2} \}[/tex]
