Perhaps you are interested in rationalising the denominator of the given problem. Let's do it.

\frac{ \sqrt{3} -  \sqrt{2}  }{ \sqrt{3} +  \sqrt{2}  }  \\  \\ multiplying \: numerator \: and \: denominator \:  \\ by \: (\sqrt{3} -  \sqrt{2}) \\  \\  \frac{( \sqrt{3} -  \sqrt{2} ) }{ (\sqrt{3} +  \sqrt{2}  )}  \times  \frac{ (\sqrt{3} -  \sqrt{2}  )}{ (\sqrt{3}  -   \sqrt{2}  )}  \\  \\  =   \frac{{( \sqrt{3}  -  \sqrt{2} )}^{2} }{ { (\sqrt{3} })^{2}  -  {(  \sqrt{2} })^{2} }  \\  \\  =  \frac{ { (\sqrt{3} )}^{2} +   { (\sqrt{2} )}^{2}   - 2 \sqrt{3 \times 2}  }{3 - 2}  \\  \\  =  \frac{3 + 2 - 2 \sqrt{6} }{1}  \\  \\  = 5 - 2 \sqrt{6}
