通分x-1/x^2+2x+1与2/x^2-1通分x-1/x^2+2x+1与2/x^2-1通分x-1/x^2+2x+1与2/x^2-1x²+2x+1=(x+1)²x²-1=
通分x-1/x^2+2x+1与2/x^2-1
通分x-1/x^2+2x+1与2/x^2-1
通分x-1/x^2+2x+1与2/x^2-1
x²+2x+1=(x+1)²
x²-1=(x+1)(x-1)
所以最简公分母是(x+1)²(x-1)
所以
(x-1)/(x²+2x+1)=(x-1)²/(x+1)²(x-1)
2/(x²-1)=2(x+1)/(x+1)²(x-1)
x-1/x^2+2x+1=(x-1)/(x+1)²=(x-1)²/(x+1)²(x-1)
2/x^2-1=2/(x+1)(x-1)=2(x+1)/(x+1)²(x-1)
通分x/(2+2x)与1/(x^2-x)
通分1/x^2-4与x/4-2x
通分（x+2)/(x^2-2x)与(x-1)/(x^2-4x+4)
3x/(x-1)(x-2)与3+x/(x-1)(2-x)分式通分
通分：x+1/x-2; x-2/x+1
x/2(x+1),1/x^2-x通分
x/2(x+1)和1、x^2-x通分
通分 x/2(x+1),1/x²-x
通分：x/1,x/x+1,2/3x
通分:x^3/x-1-x^2-x
x/x^2-4,x-1/(x+2)^2 通分x/x^2-4,x-1/(x+2)^2通分
通分x+4/x*x+4x与x-5/x(x-5)-2(x-5)
通分x+1/x(x-1),x/x^2-1,2/x^2-2x+1
通分x+1/x(x-1),x/x^2-1,2/x^2-2x+1
通分：1/x²-x,x/1-2x+x²,2/x²-x-2
通分 1/x²-4与x/4-2x x/(x-1)²与1/x²-1
通分x-1/x^2+2x+1与2/x^2-1
通分：1/x^2+x与1/x^2-x,要最简公分母
