设x²+xy=3,xy+y²=2,求2x²-xy-3y²的值
已知x²+xy=3,xy+y²=-2,则2x²-xy-3y²的值为多少?
因式分解x²+xy-6y²
若x²+xy-2y²=0,则x²+3xy+y²/x²+y²
x²+xy-2y²=0则x²+3xy+y²/x²+y²
问已知x²+y²=7,xy=-2,求5x²-3xy-4y²-11xy-7x²+2y²的值那些&sup都是平方哈,今晚要用
(x+3y)²+(2x+6y)(3y-4x)+(4x-3y)²还有几题:a四次方-6a²-27—56x³yz+14x²y²z-21xy²z²5m(x-y)²+10n(y-x)³

计算:4xy²-3x²y-{3x²y-[2xy²-4x²y+2(x²y-2xy²)]急
已知x²+y²=3xy且xy≠0,求x²y-²+x-²y²的值.(过程,跪等)
分式的除法运算x²-4y²/x²+y²+2xy÷2y+x/x²+xy
若X分之2=Y分之3,则分式7X²-Y²分之X²-2XY+3Y²
已知x²y²+x²+y²=10xy-16 求x,y
