(2/5X-3/5Y)(5/2X-5/3Y)=?
(2/5X-3/5Y)(5/2X-5/3Y)=?
(2/5X-3/5Y)(5/2X-5/3Y)=?
(2/5X-3/5Y)(5/2X-5/3Y)
=2/5x*5/2x-2/5x*5/3y-3/5y*5/2x+3/5y*5/3y
=x^2-2/3xy-3/2xy+y^2
=x^2-13/6xy+y^2
(x-y)^3×(y-x)^4+(x-y)^2×(y-x)^5
化简:5(x-y)+2(x+y)-3(x-y)
2(x-y)+3(x+y)2-5(x-y)-8(x+y)2-(x-y)
(2x+y)²+(x+3y)(x-3y)-x(5x+8y)因式分解
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)
3x(2x+y)-2x(x-y),其中x=1,y=1/5
先化简,再求值 [2/3x - 2/x+y(x+y/3x -x-y)]*x/x-y,其中5x+3y=0
【(x+2y)^2-(x-y)(3x+y)-5y^2】÷2x化简带过程
化简2x-(5x-3y)+(7x-y)
(2/3x-2/x+y(x+y/3x-x-y))÷x-y/x,其中5x+3y=0
[(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
[(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)
[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
