你好，

(x+y)²-x²y²
=(x+y)²-(xy)²
=(x+y+xy)(x+y-xy)(利用平方差公式)

因式分解:(x+y)^2-x^2y^2=答：(x+y)^2-x^2y^2 =(x+y+xy)(x+y-xy)

因式分解x^2(x+y)^2-x^2y^2答：x^2(x+y)^2-x^2y^2 =x^2[(x+y)^2-y^2]=x^2[(x+y)-y][(x+y)+y]=x^2(x+y-y)(x+y+y)=x^3(x+2y)

因式分解 (x^2+y^2)-x^2y^2答：(x^2+y^2)-x^2y^2=1-(x^2-1)(y^2-1)=（1+根号-(x^2-1)(y^2-1))(1+根号-(x^2-1)(y^2-1))

(x^2+y^2)^2-x^2 y^2 因式分解答：(x^2+y^2)^2-x^2 y^2（这是平方差公式）=(x^2+y^2+xy)(x^2+y^2-xy)

x^2-y^2-(x+y)^2因式分解答：x^2-y^2-(x+y)^2 =x²-y²-(x²+2xy+y²)=x²-y²-x²-2xy-y²=-2xy-2y²=-2y(x+y)

分解因式 (x+y)^2(x-y)^2-x^2y^2答：=[(x+y)(x-y)+xy][(x+y)(x-y)-xy]=(x²+xy-y²)(x²-xy-y²)
