Bentuk sederhana dari √2-√3/√2+2√3=.... Tolong bantu!!!

[tex] \frac{ \sqrt{2} - \sqrt{3} }{ \sqrt{2} + 2 \sqrt{3} } \times \frac{ \sqrt{2 } - 2 \sqrt{3} }{ \sqrt{2} - 2 \sqrt{3} } \\ \\ = \frac{2 - 2 \sqrt{6} - \sqrt{6} - 3}{2 - 2 \sqrt{6} + 2 \sqrt{6} - 12 } \\ \\ = \frac{ - 1 - 3 \sqrt{6} }{ - 10} \\ [/tex]
