因式分解:(x+y)∧2+4(x-1)∧2-4(x∧2-y∧2)
因式分解x²(x-2y)+y²(2y-x)
因式分解:16(x+ y)∧2 +121(x-y)∧2-88(x +y)(x-y)
(x-y)(x-y-2)+2因式分解
x(x-y)-y(y-x)+(x-y)²因式分解
已知x+y=1,xy=-2分之1,利用因式分解求:x(x+y)(x-y)-x(x+y)²的值
因式分解 (1).(x+y)(x+y-6)+9 (2).x²-16y²-x-4y
4x(y-x)-y^2因式分解
怎么因式分解6(x-y)-9-(x-y)∧2
1、(x-1分之x²)-x-1(因式分解);2、x²(x-y)²-4(y-x)²
把4(x-y+1)+y(y-2x)因式分解
因式分解-1/4x^3+x^2y-x^2y
因式分解:4x²(x-y)-2x(y-x)
