Answer 1

Ответ:

• (6x² - 5x + 9) - (3x² + x - 7) = 6x² - 5x + 9 - 3x² - x + 7 = 3x² - 6x + 16
• -3m(m³ - 8m² + 9) = -3m⁴ + 24m³ - 27m
• (y - 2)(2y + 3) = 2y² + 3y - 4y - 6 = 2y² - y - 6
• 15a⁵ + 3a²(8a - 5a³) = 15a⁵ + 24a³ - 15a⁵ = 24a³
• 2c(3c - 7) + (c - 1)(c + 4) = 6c² - 14c + c² + 4c - c - 4 = 7c² - 9c - 4
