hasil dari [tex]( \sqrt{3} + \sqrt{2} )( \sqrt{3} - \sqrt{2} ) \div 2 - \sqrt{3} [/tex] adalah?

[tex]( \sqrt{3} + \sqrt{2} )( \sqrt{3} - \sqrt{2} ) \div 2 - \sqrt{3} \\ = (3 + \sqrt{6} - \sqrt{6} - 2) \div 2 - \sqrt{3} \\ = 1 \div 2 - \sqrt{3} \\ = \frac{1}{2} - \sqrt{3} \\ \\ [/tex]
Maaf kalau salah ...
