X(5-Y)-Y(3-X)
X(5-Y)-Y(3-X)
X(5-Y)-Y(3-X)
=5X-XY-(3Y-XY)
=5X-XY-3Y+XY
=5X-3Y
=5x-xy-3y+xy
=5x-3y
x(5-y)-y(3-x)
=5x-xy-3y+xy
=5x-3y
如果你觉得我的回答比较满意,希望你给予采纳,因为解答被提问者采纳是对我们答题者的肯定,这也是我们孜孜不倦愿意为之付出的动力!
(x-y)^3×(y-x)^4+(x-y)^2×(y-x)^5
(x+y)^6/(x+y)^4-(x-y)^5/(x-y)^3 化简 ..
2(x-y)+3(x+y)2-5(x-y)-8(x+y)2-(x-y)
[(x+y)(x-y)-(x-y)的平方+2y(x-y)]除以(4y)请帮我一下写两道计算题[(x+y)(x-y)-(x-y)的平方+2y(x-y)]除以(4y)[(3x+2y)(3x-2y)-(x+2y)(5x-2y)]除以(4x)
-3(x-y)(x-y)+3(x-y)
2(x-y)²-3(x-y)(-y-x)
5(x-y)³-3(x-y)²+7(x-y)-5(x-y)³+(x-y)²-5(x-y),其中,x-y=1/3.5(x-y)³-3(x-y)²+7(x-y)-5(x-y)³+(x-y)²-5(x-y),其中,x-y=1/3先化简,再求值;
先化简,再求值 [2/3x - 2/x+y(x+y/3x -x-y)]*x/x-y,其中5x+3y=0
(4x-3y)-[(-13y-x)+(x-y)]-5x
把(x+y)、(x-y)看作整体,进行合并同类项;3(x-y)-4(x+y)+5(x-y)-(x+y).
若3x-5y=0,则x+y/x=(),x-y/y=(),2x-3y/2x+3y=( )
((x+2y)x^2+(x-y)(3x-y)-5y^2)÷2x
若x-y分之x+y=3,求式子x+y分之5(x-y)—2(x-y)分之x+y的值
3(x-1)³y-(1-x)³z m(x-y)²-x+y x²(x+y)(y-x)-xy(x+y)(x-y) 因式分解
y(x+y)+(x-y)²-(x+y)(x-y),其中x=-1/3,y=3
(5)若x/2=y/3(y不为0)则x/y=____,x+y/y=___,y/x-y=___.
(2x-3y)(x+5y)
(5x+2y)(3x-2y)
