giải các bất phương trình sau:
1) \(\frac{3x-4}{x-2}\)>1
2) \(\frac{2x^2-4x+3}{x^2-x-6}\)+\(\frac{1}{2}\)> 0
3) 2x - \(\frac{4x}{1-x}\)< \(\frac{4}{x-1}\)- 2
4) \(\frac{x-3}{x+1}\)> \(\frac{x+5}{x-2}\)
5) \(\frac{x+1}{x-1}\)+ 2 > \(\frac{x-1}{x}\)
giúp em với mng!!!
1, \(\frac{3x-4}{x-2}>1\\ \frac{3\left(x-2\right)}{x-2}+\frac{2}{x-2}>1\\ 3+\frac{2}{x-2}>1\\ \frac{2}{x-2}>-2\\ \frac{1}{x-2}>-1\)
\(x-2< -1\\ x< 1\)
