Ответ:
x1 = 1,6
x2 = -1
Объяснение:
(4x + 5) / (x + 2) = (2x - 7) / (3x - 6)
(4x + 5) (3x - 6) = (x + 2) (2x - 7)
12x² - 24x + 15x - 30 = 2x² - 7x + 4x - 14
12x² - 9x - 30 = 2x² - 3x - 14
10x² - 6x - 16 = 0
D = b² - 4ac
D = (-6)² - 4 * 10 * (-16)
D = 676
x = (-b ± √D) / 2a
x1 = (6 + 26) / 20
x2 = (6 - 26) / 20
x1 = 1,6
x2 = -1
