x^2(3x+5y)^2-y^2(5x+3y)^2
x^2(3x+5y)^2-y^2(5x+3y)^2

x^2(3x+5y)^2-y^2(5x+3y)^2
x²(3x+5y)²-y²(5x+3y)²
=[x(3x+5y)]²-[y(5x+3y)]²
=(3x²+5xy)²-(5xy+3y²)²
=[(3x²+5xy)+(5xy+3y²)][(3x²+5xy)-(5xy+3y²)]
=(3x²+5xy+5xy+3y²)(3x²+5xy-5xy-3y²)
=(3x²+10xy+3y²)(3x²-3y²)
=3(3x+y)(x+3y)(x+y)(x-y)

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) (2x-3y)-(5x-y) (2X-3y)-(5x-y) (2x-5y)(3x+y) 因式分解(x-2y)(x-3y)+(x-4y)(x-5y)+（x-3y)(x-5y)+(x-2y)(x-4y) (2x+y)²+(x+3y)(x-3y)-x(5x+8y)因式分解 [2(x-y)^5-8(x-y)^2(x+y)+6y(x-y)^2]÷2(x-y)^2[2(x-y)^3-8(x-y)^2(x+y)+6y(x-y)^2]÷2(x-y)^2 [(x+2y)(x-2y)-(2x-y)^2+(3x-y))2x-5y)]/(-x)我急用 [(x+2y)(x-2y)-(2x-y)²+(3x-y(2x-5y)]/(-x)的解答 (5x+2y)(5x-2y)-(3x+2y)(3x-2y) 2(2x+3y)(3x+2y)-(6x-y)(2x-5y) 化简：[(x+2y)^2-(x+y)(3x-y)-5y^2]/2x (2x -y)(3x-2y)+(y-x)(2x-5y) (2x-y)(3x-2y)+(y-x)(2x+5y) x+y/2+x-y/6=5 2(x+y)-3(x-y)=-2 (2x-y)(3x-4y)-2(x-y)(2x-5y)简便运算 5/4(x+y)(-x-y)^3*[-4/3(x-y)]*[-3/5(y-x)^2]
