Answer 1

Ответ:

$\frac{2m - 3x}{ {x}^{2} - {m}^{2} } + \frac{x + 6m}{ {m}^{2} - {x}^{2} } = \frac{2m - 3x}{ {x}^{2} - {m}^{2} } + \frac{x + 6m}{ - ( {x}^{2} - {m}^{2} ) } = \\ = \frac{2m - 3x}{ {x}^{2} - {m}^{2} } - \frac{x + 6m}{ {x}^{2} - {m}^{2} } = \frac{2m - 3x - x - 6m}{ {x}^{2} - {m}^{2} } = \\ = \frac{ - 4x - 4m}{ {x}^{2} - m {}^{2} } = - \frac{4(x + m)}{(x + m)(x - m)} = - \frac{4}{x - m} = \frac{4}{m - x}$
