Cevap:
[tex]-12\sqrt{2}[/tex]
Adım adım açıklama:
[tex]a=3-\sqrt{2} \\\\a^2=(3-\sqrt{2})^2=3^2-2.3.\sqrt{2} +(\sqrt{2} )^2=9-6\sqrt{2} +2=11-6\sqrt{2} \\\\b=3+\sqrt{2}\\\\b^2=(3+\sqrt{2})^2=3^2+2.3.\sqrt{2} +(\sqrt{2} )^2=9+6\sqrt{2} +2=11+6\sqrt{2}\\\\a^2-b^2= (11-6\sqrt{2})-(11+6\sqrt{2})=-12\sqrt{2}[/tex]
