x₁ = –12, x₂ = –2, x₃ = 2
Пошаговое объяснение:
x³ + 12x² – 4x – 48 = 0
x²(x + 12) – 4(x + 12) = 0
(x² – 4)(x + 12) = 0
(x – 2)(x + 2)(x + 12) = 0
x₁ = –12, x₂ = –2, x₃ = 2
Пошаговое объяснение:
x³ + 12x² – 4x – 48 = 0
x²(x + 12) – 4(x + 12) = 0
(x² – 4)(x + 12) = 0
(x – 2)(x + 2)(x + 12) = 0
x₁ = –12, x₂ = –2, x₃ = 2
