Пошаговое объяснение:                                                                                       $\displaystyle\ \Large \boldsymbol{(a+b)^2=a^2+2ab+b^2} \\\\( (\sqrt{\!\!\!\!\!\diagup m^{ \ 2\!\!\!\!\!\diagup}}) +\sqrt{2} )^2=(|m|+\sqrt{2} )^2=m^2+2\sqrt{2}|m|+2=> \\\\\\(\sqrt{m^2} +\sqrt{2} )^2=m^2\pm2\sqrt{2}m+2$
