xy的三次方-2x²y²+x的三次方y=?
xy的三次方-2x²y²+x的三次方y
=xy(y²-2xy+x²)
=xy(x-y)²
xy的三次方-2x²y²+x的三次方y
=xy(y^2-2xy+x^2)
=xy(x-y)^2
xy的三次方-2x²y²+x的三次方y
=xy(y²-2xy+x²)
=xy(x-y)²
xy的三次方-2x²y²+x的三次方y=?
xy的三次方-2x²y²+x的三次方y
=xy(y²-2xy+x²)
=xy(x-y)²
xy的三次方-2x²y²+x的三次方y
=xy(y^2-2xy+x^2)
=xy(x-y)^2
xy的三次方-2x²y²+x的三次方y
=xy(y²-2xy+x²)
=xy(x-y)²
