x^2-7xy+12y^2=0(y不等于0),求x:y的值x^2-7xy+12y^2=0(y不等于0),求x:y的值x^2-7xy+12y^2=0(y不等于0),求x:y的值x²-7xy+1
x^2-7xy+12y^2=0(y不等于0),求x:y的值
x^2-7xy+12y^2=0(y不等于0),求x:y的值
x^2-7xy+12y^2=0(y不等于0),求x:y的值
x²-7xy+12y²=0
→(x/y)²-7(x/y)+12=0
→x/y=4或x/y=3
即x:y=4:1,或x:y=3:1.
已知x^2-7xy+12y=0,且x.y不等于0,求x^2-2xy+y^2/2xy的值
x^2-7xy+12y^2=0(y不等于0),求x:y的值越快越好,
x^2-7xy+12y^2=0(y不等于0),求x:y的值
已知x^2+xy-2y^2=0 (x不等于0,y不等于0),求x/y-y/x-(x^2+y^2)/xy的值
已知7 x^2 + 5y x^2=12xy,并且xy不等于0,则可求出()的值(1)xy(2)x/y(3)x+y(4)x-y为什么?
已知x-y不等于0,x^2-x=7,y^2-y=7,求x^3+y^3+x^2y+xy^2的值

已知2x^2+5xy-7y^2=0,且y不等于0 求x/y的值
2X的平方-5XY-12Y的平方=0(Y不等于0)求Y分之X
已知x*x-2xy-3y*y=0且x不等于0 y不等于0,那么5x-4y/5x+4y=
已知7x^2+5y^2=12xy,并且xy不等于0,求x/y 和x-y的值x/y=5/7, x-y=0求详解过程,感激不尽!
1若x+2y=0 ,xy不等于0,求分式 x^2+2xy / xy+y^2
若x+2y=0,xy不等于0,求分式x²+2xy/xy+y²的值
