ТЕОРЕМА ВИЕТА помогите прошу срочно 9 класс надо решить только НА РОЗОВОМ ФОНЕ

Answer 1

Ответ:

x² - 6x - 7 = 0

x1 + x2 = 6

x1 * x2 = -7

x1 = 7

x2 = -1

x² + 4x - 5 = 0

x1 + x2 = -4

x1 * x2 = -5

x1 = -5

x2 = 1

x² + 4x - 21 = 0

x1 + x2 = -4

x1 * x2 = -21

x1 = -7

x2 = 3

x² - 6x + 5 = 0

x1 + x2 = 6

x1 * x2 = 5

x1 = 5

x2 = 1

x² - 8x - 33 = 0

x1 + x2 = 8

x1 * x2 = -33

x1 = 11

x2 = -3
