把x-y,合并同类项:5(x-y)+3(x-y)-7(x-y)=把x-y,合并同类项:5(x-y)+3(x-y)-7(x-y)=把x-y,合并同类项:5(x-y)+3(x-y)-7(x-y)=&nbs
把x-y,合并同类项:5(x-y)+3(x-y)-7(x-y)=
把x-y,合并同类项:5(x-y)+3(x-y)-7(x-y)=
把x-y,合并同类项:5(x-y)+3(x-y)-7(x-y)=
把x-y,合并同类项:5(x-y)+3(x-y)-7(x-y)=
把x-y看成一个整体,合并同类项:5(x-y)+3(x-y)-7(x-y)
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).
合并同类项:-3x+2y-5x-7y
3x+2y-5(x+y)合并同类项
-x-5y+3x-2y合并同类项.
2x-3y+5x+7y合并同类项
把x、y当做一个因式,合并2(x-y)的平方-3(x-y)+5(x-y)的平方+5(x-y)中的同类项.
合并同类项5(x-y)+2(x-y)-3(x-y)
x-(3x+y)+(x-5y)去括号,合并同类项
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).
合并同类项3(x-y)^4-(2(x-y)^4-5(X-Y)^4)-(X-Y)^4合并同类项3(x-y)^4-(2(x-y)^4-5(X-Y)^4)-(X-Y)^4
3x+2y合并同类项
把x-y看作一个整体,合并同类项3(y-x)+2(x-y)+(y-x)-(x-y)谢谢了,
把x-y看做一个整体,合并同类项. 3(y-x)^2+2(x-y)+(y-x)-(x-y)^2
合并同类项-5/3(x+y)²-6(x+y)+3(x+y)²+4/3(x+y)
(5x-4y-3xy)+(8x+y-2xy)合并同类项
把(x-y),(a+b)作为一个因式,合并同类项:3(x-y)-9(x-y)-8(x-y)+6(x-y)-1
