Question

(3/x-1 - 2/x+1)* 1-x^2/x^1+5x​

Answer 1

Пошаговое объяснение:

$( \frac{3}{x - 1} - \frac{2}{x + 1} ) \times \frac{1 - x {}^{2} }{x {}^{1} + 5x} \\ \frac{3(x + 1) - 2(x - 1)}{(x - 1)(x + 1)} \times \frac{(1 - x)(1 + x)}{x + 5x} \\ \frac{3x + 3 - 2x + 2}{x - 1} \times \frac{ - (x - 1) \times 1}{6x} \\ \frac{(x + 5) \times ( - 1)}{6x} \\ \frac{ - x - 5}{6x} = \frac{ - x + 5}{6x}$
