数学(x-y)^5*(y-x)^3*(x-y)^2谢谢 还有步骤! 数学多项式题急求[x-3y}×{x-5y} 和{2x-3y}×{3x-5y}仔细点急啊! 初中数学：若|X|=3,|y|=5,且|x-y|=x-y,求x-y的值. （x+y-5)*（x+y-5)+（x-y+3)=0 x*x-y*y 已知:3x-5y=0,求x/y,x-y/y,x-y/x (2x+y)(2x-3y)-3x(2x+y)初一数学因式分解过程 初二数学已知(x-y):y=2:3,求(2x+5y):(3x-y)的值 初一数学(x+3y-2)(2x-y) 化简:5(x-y)+2(x+y)-3(x-y) (y-x)(x-y)^3(y-x)^5怎么算 已知x-y/x+y=3,求代数式5(x-y)/x+y-x+y/2(x-y) (3x-y)(3y+x)-(x-y)(x+y) (2x-3y)-(5x-y) (2X-3y)-(5x-y) (2x-5y)(3x+y) (2x+y)²+(x+3y)(x-3y)-x(5x+8y)因式分解 计算(x+y)(x-y)(x+y)3次方(x-y)5次方计算(x+y)×(x-y)×(x+y)3次方×(x-y)5次方 因式分解(x-2y)(x-3y)+(x-4y)(x-5y)+（x-3y)(x-5y)+(x-2y)(x-4y)
