Answer:
[tex]6\sqrt{2}-2\sqrt{30}+6-2\sqrt{15}[/tex]
Step-by-step explanation:
[tex](\sqrt{12} +\sqrt{6} )(\sqrt{6}-\sqrt{10} )[/tex]
[tex]\ \sqrt{12} \sqrt{6} -\sqrt{12} \sqrt{10} +\sqrt{6} \sqrt{6} -\sqrt{6} \sqrt{10}[/tex]
[tex]\sqrt{72} -\sqrt{120} +\sqrt{36} -\sqrt{60}[/tex]
[tex]6\sqrt{2}-2\sqrt{30}+6-2\sqrt{15}[/tex]
