[tex]\frac{8}{2\sqrt{2}} -\frac{6}{2\sqrt{2} } + \frac{9}{\sqrt{2} } - \frac{12}{\sqrt{2} } + \frac{7}{3\sqrt{2} } + \frac{3\sqrt{2} }{2\sqrt{2} } =[/tex]
[tex]\frac{2}{2\sqrt{2} } - \frac{3}{\sqrt{2} } + \frac{7*2\sqrt{2}+3\sqrt{2}*2\sqrt{2} }{3\sqrt{2}*2\sqrt{2} } =[/tex]
[tex]\frac{2-6}{2\sqrt{2} } +\frac{14\sqrt{2}+ 12 }{12} =[/tex]
[tex]-\frac{4\sqrt{2} }{4} +\frac{2(7\sqrt{2}+6) }{12} =[/tex]
[tex]-\frac{6\sqrt{2}+ 7\sqrt{2}+6 }{6} =[/tex] [tex]\frac{\sqrt{2}+6 }{6} [/tex]
