Question

2+x²/x³+1- 1-x/1-x+x² - 1/x+1 скоротити дріб​

Answer 1

Ответ:

$2 + \frac{ {x}^{2} }{ {x}^{3} } + 1 - 1 - \frac{x}{1} - x + {x}^{2} - \frac{1}{x} + 1 = 3 + \frac{ {x}^{2} }{ {x}^{3} } - 2x + {x}^{2} - \frac{1}{x} = 3 + \frac{1}{x} - 2x + {x}^{2} - \frac{1}{x} = 3 - 2x + {x}^{2} = {x}^{2} - 2x + 3$
