移项,合并同类项
{(x,y) |x|+|y|
x>y?x:y
(X+y )²-8(x+y)+48
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-y/x-x+y/y-(x+y)(x-y)/y² y/x=2
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)
x+y
(x+y)
|x+y|
x y x+yy x+y xx+y x y
化简y(x+y)+(x+y)(x-y)-x^2
