解方程:1.x/x+1-1=3/(x+1)(x-2) 2.3/x+2+1/x=4/x²+2x 3.2/3+x/

1.x/x+1-1=3/(x+1)(x-2)两边乘以(x+1)(x-2)得x(x-2)-(x+1)(x-2)=3x²-2x-x²+x+2=3-x=1x=-1检验:x=-1是增根2.

解方程x(x-1)(x-2)(x-3)(x-4)=24

题目应该是(x-1)(x-2)(x-3)(x-4)=24,不然解不了[(x-1)(x-4)][(x-2)(x-3)]=24[x^2-5x+4][x^2-5x+6]=24设x^2-5x+5=y所以(y-

解方程:根号4x^2+4x+1-根号x^2+x+3=根号x^2+x-2.

记a=x^2+x,方程化为√(4a+1)-√(a+3)=√(a-2)√(4a+1)=√(a-2)+√(a+3)平方:4a+1=2a+1+2√(a-2)(a+3)a=√(a-2)(a+3)再平方a^2=

解分式方程:x-3/x-1-x-4/x-2=x-5/x-3-x-6

(x-3)(x-2)-(x-4)(x-1))/((x-1)(x-2))=((x-5)(x-4)-(x-6)(x-3))/((x-3)(x-4))2/((x-1)(x-2))=2/((x-3)(x-4)
