(x^2+16y^2)^2-64x^2y^2 因式分解
(x^2+16y^2)^2-64x^2y^2 因式分解
(x^2+16y^2)^2-64x^2y^2 因式分解
(x^2+16y^2)^2-64x^2y^2
=(x²+16y²+8xy)(x²+16y²-8xy)
=(x+4y)²(x-4y)²
(x^2+16y^2)^2-64x^2y^2
=(x^2+16y^2+8xy)(x^2+16y^2-8xy)
=(x+4y)^2 (x-4y)^2
=(x^2-16y^2)^2
(x^2+16y^2)^2-64x^2y^2
=(x^2+16y^2)^2-（8xy ）²
=[(x²+16y²)+8xy ][(x²+16y²)-8xy ]
=(x+4y)²(x-4y)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
(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)
因式分解x(x+y)(x-y)-x(x+y)^2
(x+y)^2-16(x-y)^2
(x+y)^2-16(x-y)^2
16-8（x-y)+(x-y)2
[(x-y)^2-(x+2y)(x-2y)]/y
计算:y-x分之x+y+x-y分之y-y-x分之2x-y
x^2(x-y)+(y-x)
x(x-y)2-(y-x)3
【(x-y)^2+(x+y)(x-y)】除以 2x
[(x-y)²+(x+y)(x-y)]除以2x
化简：[(x+y)(x-y)(x+y)^2-2y(x-2y)](-2y) 谢谢!
[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
