Помогите решить))) x³+6x²=4x+24
Х³ + 6х² = 4х + 24 (х³ + 6х²) - (4х + 24) =0 х² * (х + 6) - 4 * (х + 6) = 0 (х + 6) * (х² - 4) = 0 (х + 6) * (х - 2) * (х + 2) = 0 х + 6 = 0 х - 2 = 0 х + 2 = 0 х₁ = - 6 х₂ = 2 х₃ = - 2 Ответ: - 6; - 2; 2
x^3 + 6x^2 = 4x + 24 x^2( x + 6 ) - 4( x + 6 ) = 0 ( x^2 - 4 )( x + 6 ) = 0 ( x - 2 )( x + 2 )( x + 6 ) = 0 x - 2 = 0 x = 2 x + 2 = 0 x = - 2 x + 6 = 0 x = - 6 Ответ 2 ; - 2 ; - 6
