Step-by-step explanation:

 \frac{2 +  \sqrt{5} }{3 -  \sqrt{5} }  \\  \\  \frac{2 +  \sqrt{5} }{3 -  \sqrt{5} }  \times  \frac{3 +  \sqrt{5} }{3 +  \sqrt{5} }  \\  \\  \frac{2(3 +  \sqrt{5}) +  \sqrt{5} (3 +  \sqrt{5})  }{( {3}^{2} ) -  {( \sqrt{5} })^{2} }   \\  \\  \frac{6 + 2 \sqrt{5}  + 3 \sqrt{5} + 5 }{9 - 5}  \\  \\  \frac{11 + 5 \sqrt{5} }{4}
