Помогите решить пожалусьа

Answer 1

Ответ:

$1) \frac{2a}{a - b} + \frac{2b}{ b- a} = \frac{2a}{ a- b} + \frac{2b}{ - (a - b)} = \frac{ 2a}{a - b} - \frac{2b}{a - b} = \frac{2(a - b)}{a - b} = 2$

$2) \frac{4p + c}{p {}^{2} c} + \frac{p - 4c}{pc {}^{2} } = \frac{c(4p + c) + p(p - 4c)}{ {p}^{2} {c}^{2} } = \frac{4pc + {c}^{2} + {p}^{2} - 4pc}{ {p}^{2} {c}^{2} } = \frac{ {p}^{2} + {c}^{2} }{ {p}^{2} {c}^{2} }$
