Question

Скоротити дріб: x2-8x+12/x-2

Answer 1

Ответ:

-6

Объяснение:

$\frac{2x - 8x + 12}{x - 2} = \frac{ - 6x + 12}{x - 2} = \frac{12 - 6x}{x - 2} = \frac{6 \times (2 - x)}{x - 2} = \frac{6 \times (2 - x)}{ - (2 - x)} = \frac{6}{ - 1} = - 6$

Answer 2

Ответ:

6

Объяснение:

\frac{2x - 8x + 12}{x - 2} = \frac{ - 6x + 12}{x - 2} = \frac{12 - 6x}{x - 2} = \frac{6 \times (2 - x)}{x - 2} = \frac{6 \times (2 - x)}{ - (2 - x)} = \frac{6}{ - 1} = - 6
