giải phương trình ( e cần gấp giúp e vs ạ )
1) \(\sqrt{x}\)+\(\sqrt{3x-2}\)=x2+1
2) x2-2x-2\(\sqrt{2x+1}\)-2=0
3)x2-x+2\(\sqrt{x-1}\)=0
4) 2x2+2x-1=\(\sqrt{4x+1}\)
5) 8x2-3x+6=4x\(\sqrt{3x^2+x+2}\)
6)\(\sqrt{x-2000}\)+\(\sqrt{y-2001}\)+\(\sqrt{z-2002}\)=\(\frac{1}{2}\)(x+y+z)- 3000
7) x+4\(\sqrt{x+3}\)+2\(\sqrt{3-2x}\)=1
