Question

решите уравнение:

6x3-13x2 4=0

Answer 1

6 * Х³ - 13 * Х² + 4 = 0

6 * Х³ - 13 * Х² + 6 * Х - 6 * Х + 4 = 0

Х * (6 * Х² - 13 * Х + 6) - (6 * Х - 4) = 0

Х * (2 * Х - 3) * (3 * Х - 2) - 2 * (3 * Х - 2) = 0

(3 * Х - 2) * (2 * Х² - 3 * Х - 2) = 0

(3 * Х - 2) * (2 * Х + 1) * (Х - 2) = 0

Х₁ = -1/2    X₂ = 2/3     X₃ = 2

Answer 2
