-x(x-y-8)+y(y-x-8)+8(8-x+y) 因式分解
-x(x-y-8)+y(y-x-8)+8(8-x+y) 因式分解
-x(x-y-8)+y(y-x-8)+8(8-x+y) 因式分解
原式=-x²+xy+8x+y²-xy-8y+64-8x+8y
=-x²+y²+64
这个显然不能分解
提负号啊
(x-8y)(x+y)
【2(x-y)(x-y)(x-y)-8(x-y)(x-y)(x+y)+6y(x-y)(x-y)]/2(x-y)(x-y)
计算：(x-y)^8÷(y-x)^4×(x-y)
(X+y )²-8(x+y)+48
(x-y)²-8(x-y-2)
16-8(x-y)+(x-y)平方
16-8（x-y)+(x-y)2
-8(y-x)^2×(x-y)
(2x+y)²+(x+3y)(x-3y)-x(5x+8y)因式分解
[2(x-y)^5-8(x-y)^2(x+y)+6y(x-y)^2]÷2(x-y)^2[2(x-y)^3-8(x-y)^2(x+y)+6y(x-y)^2]÷2(x-y)^2
【2(x-y)^3-8(x-y)^2(x+y)+6y(x-y)^2】/2(x-y)^2=
2x/(x-8y)(x+8y)-(x+8y)/ (x-8y)(x+8y)怎麼计算了 详细
化简(2x/(x+y)-4x/(y-x))/8x(x^2-y^2)得
(x+y)/y=8/3则x/y=__ y/x-y=___
(x+y)/y=8/3则x/y=__ y/x-y=___
x(x-y-8)+y(y-x-8)+8(8-x+y)怎样因式分解
-x(x-y-8)+y(y-x-8)+8(8-x+y) 因式分解
因式分解12y(x-y)²-8(x-y)³
