圆x^2+y^2-2(m+3)x+2(1-4m)y=0,当m变化时,求圆心轨迹方程

(Y-X)^3*(X-Y)^m+(X-Y) ^m+1*(Y-X)^2 分解因式x^m+3-2x^m+2y+x^m+1y^2 分解因式：x^m+3-2x^m+2*y+x^m+1*y^2 分解因式x^m+3-（2x^m+2）y+（x^m+1)y^2 (x-2y)^m+1/(x-2y)^m-3/(2y-x)^3怎么算 计算：(y-x)^3(x-y)^m-(x-y)^m+2(y-x) 计算：2/1-m-1/m-1.2x/x-y -y/y-x -y-2x/x-y.12/m²-9 -2/m-3 计算:(1).(2x-3y)/(y-x)-(x+2y)/(x-y) (2).[5m/(m-3)+2m/(m+3)]*(m^2-9)/m 4m(x-y)-2m^2(y-x)^3 (x-y)m次方(y-x)2m次方+(y-x)3m次方得几 计算(x-y)^m(y-x)^2m+(y-x)^3m x^n*y*(-x^2y^m) 计算题:9(x-y)^3[-1/9(x-y)^m+5](y-x)^2 X^3*y^(m-1)*x^(m+y)*y^(2n+2)=x^9y^9 已知M={(x,y)|y=-x^2+mx-1},N={(x,y)|y=-x+3,0 1、x³+x²y-x²z-xyz2、9（x²-y²）-（y-x）²3、x^m-1 -x^m+2 +x^m -x^m+1要准确率的哟~ 3m(x-y)-2（y-x）²因式分解 当m为何值时,方程组3x+2y=m,2x-y=2m+1的解x、y满足x-y=2?
