x^2(x-y)+y^2(y-x)因式分解
展开全部
x^2(x-y)+y^2(y-x)
=x^2(x-y)-y^2(x-y)
=(x-y)(x²-y²)
=(x-y)(x+y)(x-y)
=(x+y)(x-y)²
=x^2(x-y)-y^2(x-y)
=(x-y)(x²-y²)
=(x-y)(x+y)(x-y)
=(x+y)(x-y)²

解:x²(x-y)+y²(y-x)
=x²(x-y)- y²(x-y)
=(x-y)(x² - y²)【提公因式】
=(x-y)(x+y)(x-y)【平方差公式】
=(x+y)(x-y)²
OK?

x^2(x-y)+y^2(y-x)
=x^2(x-y)-y^2(x-y)
=(x-y)(x^2-y^2)
=(x-y)²(x+y)
=x^2(x-y)-y^2(x-y)
=(x-y)(x^2-y^2)
=(x-y)²(x+y)

这个题很简单,我写给你:
x²(x-y)+y²(y-x)
=x²(x-y)-y²(x-y)
=(x²-y²)(x-y)
=(x+y)(x-y)(x-y)
=(x+y)(x-y)²
x²(x-y)+y²(y-x)
=x²(x-y)-y²(x-y)
=(x²-y²)(x-y)
=(x+y)(x-y)(x-y)
=(x+y)(x-y)²
