(x^2-3x)/(x^2-6x+9)约分(x^2-3x)/(x^2-6x+9)约分(x^2-3x)/(x^2-6x+9)约分原式=x(x-3)/(x-3)²=x/(x-3)(x^2-3x)
(x^2-3x)/(x^2-6x+9)约分
(x^2-3x)/(x^2-6x+9)约分
(x^2-3x)/(x^2-6x+9)约分
原式=x(x-3)/(x-3)²
=x/(x-3)
(x^2-3x)/(x^2-6x+9)
=x(x-3)/(x-3)^2
=x/(x-3)
原式=x(x-3)/(x-3)^2
=x/(x-3)
不能随便约分,要看x是否等于3
x(x*x-6x-9)-x(x*x-8x-15)+2x(3-x)
