№6. Решите уравнения: 1) 15x² - 15x = 0; 2) 64x³ - 16x² + x = 0.

**Решение:** 1. 15x² - 15x = 0 15x(x - 1) = 0 x = 0 или x - 1 = 0 x = 0 или x = 1 2. 64x³ - 16x² + x = 0 x(64x² - 16x + 1) = 0 x = 0 или 64x² - 16x + 1 = 0 D = (-16)² - 4 * 64 * 1 = 256 - 256 = 0 x = \frac{16}{2 * 64} = \frac{16}{128} = \frac{1}{8} **Ответ:** 1) x = 0, x = 1 2) x = 0, x = \frac{1}{8}
