3-2√5/3+2√5

=>(3-2√5/3+2√5)*(3+2√5/3+2√5)

=>[3^2-(2√5)^2]/[(3+2√5)^2]

=>(9-20)/(9+20+12√5)

=>-11/(29+12√5)

Given :  \frac{3 - 2 \sqrt{5} }{3 + 2 \sqrt{5} }

= \ \textgreater \   \frac{3 - 2 \sqrt{5} }{3 + 2 \sqrt{5} }  *  \frac{3 - 2 \sqrt{5} }{3 - 2 \sqrt{5} }

= \ \textgreater \   \frac{(3 - 2 \sqrt{5})(3 - 2 \sqrt{5})  }{(3 + 2 \sqrt{5} )(3 - 2 \sqrt{5}) }

= \ \textgreater \   \frac{(3 - 2 \sqrt{5})^2 }{(3)^2 - (2 \sqrt{5})^2 }

= \ \textgreater \   \frac{9 + 20 - 12 \sqrt{5} }{9 - 20}

= \ \textgreater \   -\frac{29 - 12 \sqrt{5} }{11}



Hope this helps!
