(x^2+3x+9)/(x^2-9)+6x/(9x-x^2)-(x-1)/(6+2x)化简
化简(x^2+3x+9)/(x^3-27)+(6x)/(9x-x^2)-(x-1)/(6+2x)
化简:x平方-x-2/x平方-x-6除以x平方+4x-5/x平方+2x-10
(x/x-2)+(2/x*2+2x)-(x+6/x*2-4)化简,
化简x^2(x-1)-x(x^2+2x-6),其中x=2/1
化简（x+2)(x的平方-6x-9）-（x-5)(x-3)x
化简~(x²+3x+9/x²-27)+(6x/9x-x²)-(x-1/6+2x)(x²+3x+9/x²-27)+(6x/9x-x²)-(x-1/6+2x)注意了!是三个分式!(x²+3x+9)/(x²-27)+(6x)/(9x-x²)-(x-1)/(6+2x)
化简：[√(x^2-6x+9)/x^2-x-12]*(x^3-16x)/(x^2-3x)-1/(x+3) {x＞3}
[（2x+6）/(x^2-4x+4)]×[(x-2)/(x^2+3x)]-1/x-2化简!
化简(x-2)(x^2-6x)-x(x^2-2x-8)其中x=2快
化简x(x-1)+2x(x+1)-3x(2x-5)我是这一算的，化简x(x-1)+2x(x+1)-3x(2x-5)=x²-x+2x²+2x-6x²+15x=x+2x²-6x²+15x=18x+2x²-6x²=12x²-6x²可以相减吗，还是我算的不对了？
将[(X+3/X^2-4)-(-X/6-X-X^2)]/[1-(X^2-3X-15)/(X^2+X-6)]化简
x-x^2/6
