2x+1/x^2+x=5/6x+6怎么解2x+1/x^2+x=5/6x+6怎么解2x+1/x^2+x=5/6x+6怎么解(2x+1)/(x^2+x)=5/(6x+6)6(2x+1)=5x12x+6=5
2x+1/x^2+x=5/6x+6怎么解
2x+1/x^2+x=5/6x+6怎么解
2x+1/x^2+x=5/6x+6怎么解
(2x+1)/(x^2+x)=5/(6x+6)
6(2x+1)=5x
12x+6=5x
7x=-6
x=-6/7
= x,(5x - 1)x = 0,x = 0或1/5 6x - 2x - 3 = 0 x - (1/3)x - 1/2 = 0 x - (1/3)x + (-1/6) - (-1/6)
