Toán 6x(x-2)(x-1) + 6x^2 + 11x(x-1)=0 help :( 02/12/2021 By Alexandra 6x(x-2)(x-1) + 6x^2 + 11x(x-1)=0 help 🙁
$6x.(x-2)(x-1)+6x^2+11x.(x-1) =0 $ $⇔ 6x^3-x^2+x=0$ $⇔x.(6x^2-x+1)=0$ $⇔x=0$ Vì $6x^2-x+1$ vô nghiệm Vậy $x=0$ Trả lời
$6x.(x-2)(x-1)+6x^2+11x.(x-1) =0 $
$⇔ 6x^3-x^2+x=0$
$⇔x.(6x^2-x+1)=0$
$⇔x=0$
Vì $6x^2-x+1$ vô nghiệm
Vậy $x=0$
