x(x+y)(x-y)-x(x-y)的平方 提公因式

x(x+y)(x-y)-x(x-y)的平方 提公因式
x(x+y)(x-y)-x(x-y)的平方 提公因式

x(x+y)(x-y)-x(x-y)的平方 提公因式
x(x+y)(x-y)-x(x-y)²
=x(x-y)[(x+y)-(x-y)]
=x(x-y)(2y)
=2xy(x-y)

x(x+y)(x-y)-x(x-y)²
=x(x-y)[(x+y)-(x-y)]
=x(x-y)(2y)
=2xy(x-y)
先提公因式x(x-y)

x(x+y)(x-y)-x(x+y)的平方 {(x,y) |x|+|y| x>y?x:y 因式分解：x(x+y)(x-y)-(x+y)的平方 x^/y-x-y^/y-x化简. 化简x(y-x)-y(x-y) 行列式计算 x y x+y y x+y x x+y x y|x y x+y ||y x+y x ||x+y x y | y/(x+y)-x/(x-y) x/(x+y)(x-y)的三次方,y/(y+x)(y-x)的平方通分 x-y/x-x+y/y-(x+y)(x-y)/y² y/x=2 (y-x)²(x-y)+(x-y)的三次方+2(x-y)²(y-x) 因式分解x(x+y)(x-y)-x(x+y)^2 x(x+y)(x-y)-x(x+y)² 因式分解 x y x+yy x+y xx+y x y (3x-y)(3y+x)-(x-y)(x+y) 化简x/y(x+y)-y/x(x+y) 化简 x / y(x+y) - y / x(x+y) = 化简:(x+ y)(x-y) +(x+ y) +(x-y)
