x分之x平方减1除以x平方之x平方加x加1-搜答案-智慧作业帮

原式=(x^2-1)/x÷(x^2+x)/x^2=(x-1)(x+1)/x*x^2/x(x+1)=x-1当x=2时,原式=2-1=1

再答：把y解出来再带进去再问：可以照清楚一点吗再答：再问：谢谢，不用了

(1-x)^2/(x^2+4x+4)/(x-1)^2*(x^2+3x+2)/(x-1)=(x+1)/(x+2)(x-1)=(x+1)/(x^2+x-2)再问：是1-x的平方，不是（1-x）的平方再答：

x+2分之x平方-2x-x-1分之x平方-4X+4除以x平方-16分之x平方+4x=x(x-2)/(x+2)÷(x-2)^2/(x-1)÷[x(x+4)/(x+4)(x-4)]=[x(x-2)/(x+

化简结果x/(x+1)

原式=[(x²+2x)/(x²+4x+4)]÷[(2x²-8)/(3x+6)]÷[1/(x²-4)]=[x(x+2)/(x+2)²]÷{2(x+2)(

原式=[(1-1分之x+5)-(1-1分之x+4))+(1-1分之x+3)-(1-1分之x+2)]*[(x+3)(x+5)]\(x^2+7x+13)=[(1分之x+2)-(1分之x+3)+(1分之x+

x的平方-2x+1分之x²-1+x-2分之2x-x²除以x=（x+1）（x-1）/（x-1）²-x(x-2)/(x-2)÷x=（x+1）/(x-1)-1=(x+1-x+1

[x的平方-x分之x+1-x的平方-2x+1分之x]除以x分之1=[(x+1)/x(x-1)-x/(x-1)²]×x=(x+1)/(x-1)-x²/(x-1)²=(x&#

=[(x+1)(x-1)/(x-1)²-(x-1)/(x+1)]×(x-1)/x=[(x+1)²-(x-1)²]/(x+1)(x-1)×(x-1)/x=4x/(x+1)(

你可以手写照下来吗?看不懂再答：再问：再问：你能放大点吗再问：人呢再答：哦，我再写一遍再问：嗯再答：再问：图片好小再问：不过基本会了

（X分之X-1减X+1分之X-2）除以X平方+2X+1分之X平方-X,其中X平方-X-1=0=[((x-1)(x+1)-x(x-1)]/x(x+1)÷(x²-x-1+1)/(x+1)

(x的平方-1分之x的平方-2x+1+x分之1)除以x+1分之1=((x-1)^2/(x-1)(x+1)+1/x)*(x+1)=((x-1)/(x+1)+1/x)*(x+1)=(x-1)+(x+1)/

(x²-6x+9)/(x+1)÷(x²-9)/(x²+x)=[(x-3)²/(x+1)]×[x(x+1)/(x+3)(x-3)]=x(x-3)/(x+3)x的平

2x分之x的平方-4x+4除以x平方分之x的平方-2x+1等于2分之x,当x=0或2时,分式无意义

[(x²-4x+4)/(2x)]÷[(x²-2x+1)/x²]=[(x-2)²/(2x)]/[(x-1)²/x²]=(x-2)²x

(x+1-1/(1-X))/(X-X^2/(X-1))=(-X^2/(1-X))/(-X/(X-1))=X

〔(x^2-4x+4)/(x^2-4)〕/〔(x^2-2x)/(x+2)〕-1/x+1=〔(x-2)^2/(x+2)(x-2)〕/〔x(x-2)/(x+2)〕-1/x+1=〔(x-2)/(x+2)〕/

x的平方-1分之x除以x的平方分之x的平方=x²-(x/1)/(x²/x²）=x²-(x)/1=x²-x
