Question

Решить уравнение x^6=(3x+10)^3

Answer 1

Ответ:

= (3x+10)³

x² = 3x + 10

x² - 3x - 10 = 0

x² + 2x - 5x - 10 = 0

x · (x+2) - 5(x+2) = 0

(x+2)×(x-5) = 0

x + 2 = 0

x = 5

x1 = -2

x2 = 5

Answer 2

Ответ:

x^{6} = (3x+10)³

x² = 3x + 10

x² - 3x - 10 = 0

x² + 2x - 5x - 10 = 0

x · (x+2) - 5(x+2) = 0

(x+2)×(x-5) = 0

x + 2 = 0

x = 5

x1 = -2

x2 = 5
