9(x-y)-12(y-x)^2
3y=2x y/3=x/2 12/x=9/y y/x=?y/x=?x/y=?
x(x-y)2-(y-x)3
12y(x-y)^2-8(x-y)^3=?
因式分解:12xy^2(y-x)+xy^3(x-y)+4x^2y(x-y)
[12(x+y)^3+3(x+y)(x-y)^2]÷6(x+y)
3(x+y)-2(x-y)=11 4(x+y)+3(x-y)=9
12(x+y)^3(y-x)/【4(x+y)^2(x-y)】
4(x-y)-3(x-y)=9 5(x-y)+2(x-y)=11
81/8*(-x-y)^6*(x-y)^3*4/9(x+y)^4*(y-x)^2
计算(x-y)^7÷(y-x)^6+9-x-y)^3÷(x+y)^2
3x+y=2 -y/x+y=123x+y=2 (-y/x)+y=12
[2/3x-2/x+y(x+y/3x-x-y)]/x-y/x
化简:{2/3x-2/(x+y)[(x+y)/3x-x-y]}/(x+y)/x
计算2/3x-2/x+y(x+y/3x-x-y)/x-y/x
(3x+2y)^2-9(x-y)^2(18x^2-12xy+2y^2)/(3x-y)
化简3x-2/(x+y)[(x+y)/3x-x-y]÷(x-y)/x
化简:x-y/x+3y÷x^-y^2/x^2+6xy+9y^2-(xy/x+y)
