Nguyễn Hưng Phát · Accepted Answer

$x^3-2x^2+x$$=x^3-x^2-x^2+x$$=x^2\left(x-1\right)-\left(x^2-x\right)$$=x^2\left(x-1\right)-x\left(x-1\right)$$=\left(x^2-x\right)\left(x-1\right)$$=x\left(x-1\right)\left(x-1\right)$$=x\left(x-1\right)^2$Câu trả lời: $x^3-2x^2+x$$=x^3-x^2-x^2+x$$=x^2\left(x-1\right)-\left(x^2-x\right)$$=x^2\left(x-1\right)-x\left(x-1\right)$$=\left(x^2-x\right)\left(x-1\right)$$=x\left(x-1\right)\left(x-1\right)$$=x\left(x-1\right)^2$

Sakura Scarlet · Answer

x3-2x2+x=(x3-x2)-(x2-x)=x2(x-1)- x(x-1)=(x-1)(x2-x)=x(x-1)(x-1)=x(x-1)2Câu trả lời: x3-2x2+x=(x3-x2)-(x2-x)=x2(x-1)- x(x-1)=(x-1)(x2-x)=x(x-1)(x-1)=x(x-1)2
