9(x-y)²(x+y)+3(x+y)²(y-x)
=9(x+y)(x-y)(x+y)-3(x+y)²(x-y)
=9(x+y)²(x-y)-3(x+y)²(x-y)
=6(x+y)²(x-y)

因式分解:x²(x-y)+(y-x) (x+y)²+x+y-6因式分解 (x-y)²-(x-y)因式分解因式分解 a²（y-x)+(x-y) 9(3x-2y)²-(x-y)²,因式分解因式分解：（x+2y)²-y² 因式分解：(x-y)(3x-7y)²-4(x-y)(x+y)² (x-y)^3-(x-y)^4 因式分解 (x-y)^2-(x-y)^3因式分解 (x+y)^2-3(x-y)因式分解因式分解：9(x-y)²-25(x+y)² (x-y)²-(3x-3xy+y²)因式分解
