x三次方+5x二次方-6x=0x三次方+5x二次方-6x=0x三次方+5x二次方-6x=0x三次方+5x二次方-6x=0x(x^2+5x-6)=0x(x+6)(x-1)=0x1=1x2=-6x3=1x

x三次方+5x二次方-6x=0
x三次方+5x二次方-6x=0

x三次方+5x二次方-6x=0
x三次方+5x二次方-6x=0
x(x^2+5x-6)=0
x(x+6)(x-1)=0
x1=1 x2=-6 x3=1

x(x²+5x-6)=0
x(x-1)(x+6)=0
所以x1=0,x2=1,x3=-6

x³+5x²-6x=0
x(x²+5x-6)=0
x(x+6)(x-1)=0
x1=0, x2=-6, x3=1

以下均为正解啊
