谁能回答~`?

m(m-x)(m-y)-y(x-m)(y-m)
=m(m-x)(m-y)-y(m-x)(m-y)
=(m-x)(m-y)(m-y)
=(m-x)(m-y)^2

m(m-x)(m-y)-y(x-m)(y-m)
=m(x-m)(y-m)-y(x-m)(y-m)
=(m-y)(x-m)(y-m)
=-(m-y)^2 * (x-m)

(M-X)(M-Y)(M-Y)

分解因式：m(m-x)(m-y)-y(x-m)(y-m) (x+y)(m+n) x+y=m 5x-3y= -m 分解式子12X^2N+1Y^M+2-20X^N+1Y^2M+3 x[(x^2 +y^2)-(x+y)^2]分解因式 c语言#define M(x,y,z) x*y+z 解下列方程组｛(m+1)x+y=m 3x+(m-1)y=2 3X+Y=1+M X+3Y=1-M X+Y 0求M取值 1000x+100y+10z+m 分解因式4-12（x-y)+9(x-y)^2
