(6/x2-1)-(3/x-1)=1(6/x2-1)-(3/x-1)=1(6/x2-1)-(3/x-1)=1两边乘(x+1)(x-1)6-3(x+1)=x²-1x²+3x-4=0(
(6/x2-1)-(3/x-1)=1
(6/x2-1)-(3/x-1)=1
(6/x2-1)-(3/x-1)=1
两边乘(x+1)(x-1)
6-3(x+1)=x²-1
x²+3x-4=0
(x+4)(x-1)=0
分母x-1≠0
所以x+4=0
x=-4
两边乘(x-2)(x-3)(x-1)
2(x-1)(x-3)=3(x-1)(x-2)-(x-2)(x-3)
2x2-8x+6=3x3-9x+6-x2+5x-6
-8x+6=-4x
x=3/2
分式方程要检验
经检验,x=3/2是方程的解
7/x2+x+1/x2-x=6/x2-1
解方程:1/x2+x +1/x2+3x+2 +1/x2+5x+6 +1/x2+7x+12 +1/x2+9x+20=5/x2+11x-708解方程:1/x2+x +1/x2+3x+2 +1/x2+5x+6 +1/x2+7x+12 +1/x2+9x+20=5/x2+11x-708
6x2-[-3x2-(x-1)] 化简
x2-3x+1=0 x2/(x4-x2+1)
x2-3x-1=0,求①x2 1/x2;②x2-1/x2
1/(x2+x)+1/(x2+3x+2)+1/(x2+5x+6)+1/(x2+7x+12)=4/21x2是x的平方
解方程:X2--1/8(X2+2X)+X2+2X/3(X2--1)=11
解方程 2/(x2-x)+6/(1-x2)=7/(x2+x)x2为的平方
3/x2 -3x+2-1/x-2=1/x2 -x+4/x2 -2x
计算:x2-5x+6/x2-4x+3 + x2-4x+3/x2-2x+1 + x2-3x-4/1-x2
x+1/x=3,求x2/x4+x2+1
x2+x-6/(x2+x)+1=0怎么做
解方程x2-6/ x2-x=x-1
解方程:x2+1+x=6/x+x2
4x2-4x+1=x2+6x+9
已知x2-4x+1=0,求x2/(x2)2-3x2+1
解方程:1/x2+x +1/x2+3x+2 +1/x2+5x+6 +1/x2+7x+12 +1/x2+9x+20=5/x2+11x-708等会就要 再次坐等
解分式方程:1/(x2-2x-3) +2/(x2-x-6) +3/(x2+3x+2)=0
