x²-(x³y-2x²y²)÷(xy)
x²-(x³y-2x²y²)÷(xy)

x²-(x³y-2x²y²)÷(xy)
x²-(x³y-2x²y²)÷(xy)
=x²-x³y÷xy+2x²y²÷xy
=x²-x²+2xy
=2xy

x²-(x³y-2x²y²)÷(xy)
=x²-xy(x²-2xy)÷(xy)
=x²-(x²-2xy)
=2xy

=x²-(x²-2XY)
=2XY

x²-(x³y-2x²y²)÷(xy)=x²-xy(x²-2xy)/xy=x²-(x²-2xy)=2xy

x的平方-2x三次方y

x²-(x³y-2x²y²)÷(xy)
=x²-x²-2xy
=-2xy
