Question

Упростите. Заранее спасибо

Answer 1

Ответ:

$\displaystyle \frac{x^{3} - 4x}{5 {x}^{2} - 10x} = \frac{x(x^{2} - 4) }{5x(x - 2)} = \frac{x(x - 2)(x + 2)}{5x(x - 2)} = \frac{x(x + 2)}{5x} = \frac{x + 2}{5}.$

Answer 2

Ответ:

$\frac{x( {x}^{2} - 4) }{5x(x - 2)} = \frac{(x - 2)(x + 2)}{5(x - 2)} = \frac{x + 2}{5}$
