Ответ:
[tex]\frac{x}{x-5} + \frac{x}{x+5} = \frac{2x^2}{x^2-25}[/tex]
Объяснение:
[tex]\frac{x}{x-5}^{`x+5} + \frac{x}{x+5}^{`x-5} = \frac{x(x+5)}{(x-5)(x+5)} + \frac{x(x-5)}{(x-5)(x+5)} = \frac{x^2+5x+x^2-5x}{x^2+5x-5x-25} = \frac{2x^2}{x^2-25}[/tex]

Объяснение:
[tex]\frac{x}{x-5}^{`x+5} + \frac{x}{x+5}^{`x-5} = \frac{x(x+5)}{(x-5)(x+5)} + \frac{x(x-5)}{(x-5)(x+5)} = \frac{x^2+5x+x^2-5x}{x^2+5x-5x-25} = \frac{2x^2}{x^2-25}[/tex]
