因式分解(x-2y)(x-3y)+(x-4y)(x-5y)+(x-3y)(x-5y)+(x-2y)(x-4y)
5/4(x+y)(-x-y)^3*[-4/3(x-y)]*[-3/5(y-x)^2]
(2x-y)(3x-4y)-2(x-y)(2x-5y)简便运算
5x^3y(x-y)^3-10x^4y^3(y-x)^2因式分解
5x^3y(x-y)^3-10x^4y^3(y-x)^2
3(x+y)+2(x-y)=36 4(x+y)-5(x-y)=2
5X^3Y(X-Y)-10X^4Y^3(Y-X)^2因式分解
4(x-y)-3(x-y)=9 5(x-y)+2(x-y)=11
3(x+y)-4(x-y)=11,2(x-y)+5(x+y)=27
(x-y)^3×(y-x)^4+(x-y)^2×(y-x)^5
计算(x^8-x^7y+x^5y^3-x^4y^4+x^3y^5-x^y^7+y^8)(x^2+xy+y^2)
先化简再求值(x-y)(x-2y)+(x-2y)(x-3y)-2(x-3y)(x-4y) x=4 y=5
3(x-y)-2(x+y)-5(x-y)+4(x+y)+3(x-y) 化简合并同类项
化简:5(x-y)+2(x+y)-3(x-y)
已知x-y/x+y=3,求代数式5(x-y)/x+y-x+y/2(x-y)
化简[(3x+4y)^2-(2x+y)(2x-y)+(-x+y)(5x-y)]除以-2y,其中x=-1,y=1
[(x+y)(x-y)-(x-y)的平方+2y(x-y)]除以(4y)请帮我一下写两道计算题[(x+y)(x-y)-(x-y)的平方+2y(x-y)]除以(4y)[(3x+2y)(3x-2y)-(x+2y)(5x-2y)]除以(4x)
4x+2y-5x-y
