(3x+2y)(2x-3y)(3x+2y)(2x-3y)(3x+2y)(2x-3y)
(3x+2y)(2x-3y)
(3x+2y)(2x-3y)
(3x+2y)(2x-3y)
2(x-y)²-3(x-y)(-y-x)
化简((X-2Y)的平方+(X-Y)(x+Y)-2(X-3Y)(X-Y))除以Y
把6x(x-y)的平方+3(y-x)的立方分解因式我知道答案是6x(x-y)^2+3(y-x)^3=6x(x-y)^2-3(x-y)^3=3(x-y)^2[2x-(x-y)]=3(x-y)^2(x+y)可为什么=6x(x-y)^2-3(x-y)^3=3(x-y)^2[2x-(x-y)]
已知x-y=1,y≠0,求{(x+2y)²+(2x+y)(x+4y)-3(x+y)(x-y)}÷y的值.
(y-x)^4(x-y)^3+2(x-y)^6(y-x)
(x-y)^3×(y-x)^4+(x-y)^2×(y-x)^5
12(x+y)^3(y-x)/【4(x+y)^2(x-y)】
计算(x-y)^2×(x-y)^3×(y-x)×(y-x)^2
(x+y)/2- x-y/2=6 3(x+y)=4(x-y)
2分之x+y+3分之x-y;4(x+y)-(x-y)谢谢了,
3x+y=2 -y/x+y=123x+y=2 (-y/x)+y=12
(2x-y)乘(2x+y)+(2x-y)乘(y-4x)+2y(y-3x)
3x(x-2y)+(x+2y)(2x-y)-3y(y-2x)
2(x-y)+3(x+y)2-5(x-y)-8(x+y)2-(x-y)
(2x-y)+(x+3y)(x-3y)=
[(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)
先化简再求值 [(x-y)²+(x+y)(x-y)]÷2x,其中x=3,y=1
1.((y+2x)(-2x+y)+4(x+2y)^2)/3y 2.(2(x-y)^3-8(x-y)^2(x+y)+6y(x-y)^2)/2(x-y)^2
