因式分解:1/9x²y-1/3xy+2/9y
因式分解:1/9x²y-1/3xy+2/9y

因式分解:1/9x²y-1/3xy+2/9y
1/9x²y-1/3xy+2/9y
=y/9(x²-3x+2)
=y/9(x-1)(x-2)

答:
1/9x²y-1/3xy+2/9y
=(y/9)(x²-3x+2)
=(1/9)(x-1)(x-2)y已知集合A={x|x2-6x+8<0},B={x|(x-a)(x-3a)<0}.若A∩B=空集,求a的取值范围其它问题请采纳后追问,或者另外提问,谢谢http://zhidao.baidu.com/question/2636452253642604...
