y+9x=xy怎么因式分解成(x-1)(y-9)=9
y+9x=xy怎么因式分解成(x-1)(y-9)=9
y+9x=xy怎么因式分解成(x-1)(y-9)=9
y+9x=xy
xy-9x-y=0
xy-9x-y+9=9
(x-1)(y-9)=9
这样倒推:
(x-1)(y-9)=9
xy-9x-y+9=9
xy=y+9x
y+9x=xy xy-9x-y+9=9 x(y-9)-(y-9)=9 (y-9)(x-1)=9
y+9x=xy
xy-9x-y=0
xy-9x-y+9-9=0
(x-1)y-9(x-1)=9
(y-9)(x-1)=9
y+9x=xy,所以:xy-y-9x+9=9
即:y(x-1)-9(x-1)=9,所以:(x-1)(y-9)=9
y+9x=xy
xy-9x-y=0
x(y-9)-y=0
x(y-9)-y+9-9=0
x(y-9)-(y-9)-9=0
x(y-9)-(y-9)=9
(y-9)(x-1)=9
(x-1)(y-9)=9
y+9x=xy怎么因式分解成(x-1)(y-9)=9
