Сократите дробь: 1) x²-6x+5 2) 2x + 12 18 3) x² + 9x + 14 x² + 7x 4) 6x-6 5) x²-7x+12; x² - 3x 6) x² + 4x x²+2x-8

Ответ: Сокращение дробей.

1. \[\frac{x^2-6x+5}{x^2-6x+5} = \frac{(x-5)(x-1)}{(x-5)(x-1)} = 1\]
2. \[\frac{2x+12}{18} = \frac{2(x+6)}{18} = \frac{x+6}{9}\]
3. \[\frac{x^2+9x+14}{x^2+7x} = \frac{(x+2)(x+7)}{x(x+7)} = \frac{x+2}{x}\]
4. \[\frac{x^2 + 4x}{x^2 + 2x - 8} = \frac{x(x + 4)}{(x - 2)(x + 4)} = \frac{x}{x - 2}\]
5. \[\frac{x^2-7x+12}{x^2-3x} = \frac{(x-4)(x-3)}{x(x-3)} = \frac{x-4}{x}\]
6. \[\frac{x^2 - 3x + 2}{6x - 6} = \frac{(x - 2)(x - 1)}{6(x - 1)} = \frac{x - 2}{6}\]
