2x²y²-x的4次方-y的4次方=
2x²y²-x的4次方-y的4次方=
2x²y²-x的4次方-y的4次方=
2x²y²-x的4次方-y的4次方
=-(x^4+y^4-2x^2y^2)
=-(x^2-y^2)^2
=-(x+y)^2(x-y)^2
解2x²y²-x的4次方-y的4次方
=-(-2x²y²+x的4次方+y的4次方)
=-(x的4次方-2x²y²+y的4次方)
=-(x²-y²)²
2x^2y^2-x^4-y^4
=-(x^4-2x^2y^2+y^4)
=-(x^2-y^2)^2
=-(x+y)^2(x-y)^2
2x²y²-x的4次方-y的4次方
=(2x²y²-x)²+y²乘以(2x²y²-x)²-y²
你接着往下推吧
