x(x+y)(x-y)-x(x+y)的平方
x(x+y)(x-y)-x(x+y)的平方
x(x+y)(x-y)-x(x+y)的平方
x(x+y)(x-y)-x(x+y)的平方
=(x^2-xy)(x+y)-(x^2+xy)(x+y)
=(x^2-xy-x^2-xy)(x+y)
=-2xy(x+y)
x(x+y)(x-y)-x(x+y)²
=x(x²-y²)-x(x²+2xy+y²)
=x^3-xy²-x^3-2x²y-xy²
=-2xy²-2x²y
x(x的平方-y的平方）-x(x的平方+2xy+y的平方)
x的三次方-xy的平方-x的平方-2x的平方y-xy的平方
-2xy的平方-2x的平方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)
