(x-y)(2x+3y)-3(x+2y)(x-2y)分解因式(x-y)(2x+3y)-3(x+2y)(x-2y)分解因式(x-y)(2x+3y)-3(x+2y)(x-2y)分解因式=2x平方+xy-3
(x-y)(2x+3y)-3(x+2y)(x-2y)分解因式
(x-y)(2x+3y)-3(x+2y)(x-2y)分解因式
(x-y)(2x+3y)-3(x+2y)(x-2y)分解因式
=2x平方+xy-3y平方-3(x平方-4y平方)
=-x平方+xy+9y平方
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)]
(x-y)(2x+3y)-3(x+2y)(x-2y)分解因式
分解因式(x+y)3次方-y(x+y)平方+x平方(y+x)
3x(2x+y)-2x(x-y),其中x=1,y=1/5
把(x+y),(x-y)个作为一个整体合并同类项1,7(x+y)-2(x+y)-4(x+y)+2(x+y)2,(x-y)²+2(x-y)-(x-y)-2(x-y)²
已知x和y满足x+3y+|3x-y|=19,2x+y=6,求x,y的值
设x,y满足x+3y+|3x-y|=19,2x+y=6则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.
x(x-y)2-(y-x)3
y(x+y)+(x-y)²-x²-2y²
已知3+XY-2y=0(x≠0,Y≠0)求x/y-y/x-x+y/xy
[2/3x-2/x+y(x+y/3x-x-y)]/x-y/x
化简:{2/3x-2/(x+y)[(x+y)/3x-x-y]}/(x+y)/x
计算2/3x-2/x+y(x+y/3x-x-y)/x-y/x
化简3x-2/(x+y)[(x+y)/3x-x-y]÷(x-y)/x
解题:[(3x+2y)(3x-2y)-(x+2y)(5x-2y)]÷4x
[(3x+y)(x-y)-(2x+3y)(x-y)]*(x-y)
