x分之3-1-x分之6-x的2次方-x分之x 5

x^2-x-6分解因式得(x+2)(x-3)x^2-4分解因式得(x-2)(x+2)故(x^2-x-6分之x^2-4+x-3分之x+2)=(x-2)/(x-3)+(x+2)/(x-3)=2x/(x-3

(x-3)分之1+(6+2x)分之1-x-(x²-9)分之6=1/(x-3)+(1-x)/2(x+3)-6/(x+3)(x-3)=[2(x+3)+(1-x)(x-3)-12]/2(x+3)(

x-3分之5-x方-9分之x-2+2x-6分之x-1=5/(x-3)-(x-2)/(x^2-9)+(x-1)/2(x-3)=(10(x+3)-2(x-2)+(x-1)(x+3))/2(x+3)(x-3

x平方-6x+8=x²-2×3x+9-9+8=（x-3）²-1=（x-3-1）（x-3+1）=（x-4）（x-2）x平方+x-6=（x-2）（x+3）12+x-x平方=（4-x）（

原式=3/2(x+2)+6/(x+2)(x-2)+1/(x-2)=(3x-6+12+2x+4)/2(x+2)(x-2)=(5x+10)/2(x+2)(x-2)=5(x+2)/2(x+2)(x-2)=5

(x-1)/3-(x+2)/6=(4-x)/2等式两边同乘6得：2(x-1)-(x+2)=3(4-x)去括号：2x-2-x-2=12-3x移项：4x=16x=4

9x的2次方分之2+6x分之1-3x分之1=2/(9x²)+1/(6x)-1/(3x)括号加得对吗?=4/(18x²)+3x/(18x²)-6x/(18x²)=

(x-3)分之x-(x^2-3x)分之(x+6)+x分之1等于几?=x²/x(x-3)-(x+6)/x(x-3)+(x-3)/x(x-3)=(x²-x-6+x-3)/x(x-3)=

1)去分母得2(x-1)+3(x+1)=62x-2+3x+3=6∴x=1经检验：x=1是增根∴方程无解2)设y=(x+1)/x,∴x/(x+1)=1/y∴原方程可化为y+5/y=6∴y平方-6y+5=

原式=1/(x+1)*[(x-3)/(x+3)^2+2/(x+3)]-x/(x+3)(x-3)=1/(x+1)[3(x+1)/(x+3)^2]-x/(x+3)(x-3)=3/(x+3)^2-x/(x+

1分之6..

再问：再答：

(x-1)/(x^2+3x+2)+6/(2+x-x^2)-(10-x)/(4-x^2)=(x-1)/(x+1)(x+2)-6/(x+1)(x-2)-(x-10)/(x+2)(x-2)=[(x-1)(x

原式=1/(x-3)-1/2(x+3)-x/(x-3)²=[2(x+3)(x-3)-(x-3)²-2x(x+3)]/[2(x+3)(x-3)²]=(2x²-18

(x+1)/(x+2)-1/(x+7)=（x+2)/（x+3)-1/(X+6）(X+2-1)/(X+2)-1/(X+7)=(X+3-1)/(X+3)-1/(X+6)1-1/(X+2)-1/(X+7)=

两边乘以x(x-1)得3(x-1)+6x=73x-3+6x=79x=10x=10/9经检验：x=10/9是方程的解

本人一次只回答一个算了吧或者你分开提问x/(x+2)=x/(x-1)两边乘(x+2)(x-1)x²-x=x²+2x3x=0x=0经检验,x=0是方程的解

注:分子/分母(1/x-3)+(1/9-x^2)-(x-1/6-2x)通分:=2(x+3)/2(x+3)(x-3)+12/2(9-x^2)-(x-1)(3+x)/2(3-x)(3+x)=2x+6/2(
