Объяснение:

$\frac{m {}^{2} - {n}^{2} }{m {}^{2} + n {}^{2} } + \frac{ {m}^{2} + m {}^{2} }{m {}^{2} - n {}^{2} } - 2 = \frac{(m {}^{2} + n {}^{2} ) \times(m {}^{2} - n {}^{2})+(m {}^{2} + n {}^{2} ) \times(m {}^{2} - n {}^{2})}{(m {}^{2} + n {}^{2}) \times(m {}^{2} - n {}^{2})} - 2= \frac{2(m {}^{2} + n {}^{2}) \times(m {}^{2} - n {}^{2})}{(m {}^{2} + n {}^{2}) \times(m {}^{2} - n {}^{2})} - 2 = 2 - 2 = 0$
