x^2·(2x+y)·(2x-y)+x^2· y^2
x^2·(2x+y)·(2x-y)+x^2· y^2
x^2·(2x+y)·(2x-y)+x^2· y^2
x^2*(2x+y)*(2x-y)+x^2* y^2
=x^2*(4x^2-y^2)+x^2* y^2
=x^2*(4x^2-y^2+y^2)
=x^2*4x^2
=4x^4
x2*(4x2-y2)+x2y2=4X4(4X四次方)
原式=2xn(4x2-y2)+4xnyn
原式=X2(4X2-Y2）+X2Y2
＝4X4
=x^2·(4x^2-y^2)+x^2· y^2
=x^2·(4x^2-y^2+y^2)
=4x^4
x^2·(2x+y)·(2x-y)+x^2· y^2
=x^2[(2x)^2-y^2]+x^2y^2
=4x^4-x^2y^2+x^2y^2
=4x^4
=4x^4
过程：
原式=x^2(4x^2-y^2)+x^2y^2
=4x^4-x^2y^2=x^2y^2
=4x^4
因式分解x(x+y)(x-y)-x(x+y)^2
x-y/x-x+y/y-(x+y)(x-y)/y² y/x=2
化简y(x+y)+(x+y)(x-y)-x^2
计算2x/1-x+y/1·（2x/x+y-x-y）
(x-y)^4·(x-y)-2(y-x)³·（y-x)²怎么算,
(x+y)(x-y)-(x-y)^2如题 (x+y)(x-y)-(x-y)^2
【2(x-y)(x-y)(x-y)-8(x-y)(x-y)(x+y)+6y(x-y)(x-y)]/2(x-y)(x-y)
x^2(x-y)+(y-x)
x(x-y)2-(y-x)3
[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
计算：[(x+y/x-y)^2·(2y-2x/3x+3y)]-[(x^2/x^2-y^2)/(x/y)]今天止
【(x-y)^2+(x+y)(x-y)】除以 2x
[(x-y)²+(x+y)(x-y)]除以2x
x^2·(2x+y)·(2x-y)+x^2· y^2
计算:x+(x+y)+(x+2y)+···+(x+99y)等于?
