Question

Ajutor! $( \sqrt{3} - \sqrt{5})^{2} +2( \sqrt{3}+ \sqrt{5})( \sqrt{3}-\sqrt{5})-( \sqrt{3} + \sqrt{2})$

Answer 1

3-2√15 +5 +2(3-5)-√3-√2
3-2√15+5+6-10-√3-√2
4-2√15 -√3+√2

Answer 2

[tex]( \sqrt{3} - \sqrt{5} )^2+2( \sqrt{3} + \sqrt{5} )( \sqrt{3} - \sqrt{5} )-( \sqrt{3} + \sqrt{2} )= \\ 3+5-2 \sqrt{15}+2(3-5)- \sqrt{3}- \sqrt{2}= \\ 8- 2\sqrt{15}-4- \sqrt{3}- \sqrt{2}=2(2- \sqrt{15})- \sqrt{3}- \sqrt{2} [/tex]
