将2(x+y)-3(x-y)-4(x+y)+5(x-y)-3(x-y)合并同类项得:( )
将2(x+y)-3(x-y)-4(x+y)+5(x-y)-3(x-y)合并同类项得:( )
将2(x+y)-3(x-y)-4(x+y)+5(x-y)-3(x-y)合并同类项得:( )
将2(x+y)-3(x-y)-4(x+y)+5(x-y)-3(x-y)合并同类项得:-2(x+y)-(x-y)
也可继续化为:-3x-y
将(x-y)看成一个整体,将3(x-y)²-4(x-y)+7(x-y)-6(y-x)²-2(y-x)合并同类项.
将2(x+y)-3(x-y)-4(x+y)+5(x-y)-3(x-y)合并同类项得:( )
(y-x)^4(x-y)^3+2(x-y)^6(y-x)
(x-y)^3×(y-x)^4+(x-y)^2×(y-x)^5
12(x+y)^3(y-x)/【4(x+y)^2(x-y)】
(x+y)/2- x-y/2=6 3(x+y)=4(x-y)
2分之x+y+3分之x-y;4(x+y)-(x-y)谢谢了,
2(x-y)²-3(x-y)(-y-x)
(x-y) (x-2y)+(x+2y) (x-3y)-2(x-3y) (x-4y)=
[(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)
(x+3y-4)(2x-y)
计算(2x-3y)(x+4y)-(3x+y)(x-2y)(2x-3y)(x+4y)-(3x+y)(x-2y)
因式分解(x-2y)(x-3y)+(x-4y)(x-5y)+(x-3y)(x-5y)+(x-2y)(x-4y)
1.((y+2x)(-2x+y)+4(x+2y)^2)/3y 2.(2(x-y)^3-8(x-y)^2(x+y)+6y(x-y)^2)/2(x-y)^2
(2x+3y)(2x-y)-4y(2x-y) 因式分解
x²/xy-x/y 3x/4x+y - x-2y/4x+y (1-y/y+x)÷x/y²-x²
将多项式(x+y)^2-4(x+y)+4因式分解
(x/x+y +2y/x+y)乘以xy/ x+2y除以(1/x+1/y)(2)(3x^2/4y)^2乘以2y/3x+ x^2/2y^2除以2y^2/x
