 \frac{2 \sqrt{45}  - 3 \sqrt{20} - 10 \sqrt{125}  }{ 2 \sqrt{5} }

  = \frac{2 \sqrt{9 \times 5}  - 3 \sqrt{4 \times 5} - 10 \sqrt{25 \times 5}  }{2 \sqrt{5} }

 =  \frac{2 \times 3 \sqrt{5}  - 3 \times 2 \sqrt{5}  - 10 \times 5 \sqrt{5} }{2 \sqrt{5} }

  = \frac{6 \sqrt{5} - 6 \sqrt{5}  - 50 \sqrt{5}  }{2 \sqrt{5} }

  = \frac{ - 50 \sqrt{5} }{2 \sqrt{5} }

 = - 25
