a(x-y)-b(y-x)+c(x-y)怎么算?a(x-y)-b(y-x)+c(x-y)怎么算?a(x-y)-b(y-x)+c(x-y)怎么算?a(x-y)-b(y-x)+c(x-y)=a(x-y)+
a(x-y)-b(y-x)+c(x-y)怎么算?
a(x-y)-b(y-x)+c(x-y)怎么算?
a(x-y)-b(y-x)+c(x-y)怎么算?
a(x-y)-b(y-x)+c(x-y)
=a(x-y)+b(x-y)+c(x-y)
=(x-y)(a+b+c).
a(x-y)-b(y-x)+c(x-y)
=a(x-y)+b(x-y)+c(x-y)
=(x-y)(a+b+c)
a(x-y)-b(y-x)+c(x-y)
解:原式=a(x-y)+b(x-y)+c(x-y)
=(a+b+c)(x-y)
a(x-y)(x+y)-b(y-x)(x+y)-c(x-y)^2(y+x)提取公因式
A.(x+y)(x-y) B.(x-y)(-x-y) C.(-x+y)(x+y) D.(x+y)(-x-y)可以用完全平方公式计算的是?
(-x+y)(y²+x²)再乘以( )就等于x`4-y`4 A.X-Y B.X+Y C.-X+Y D.-X-YA.X-Y B.X+Y C.-X+Y D.-X-Y`表示次方
X=a*b*c,Y=a*b*c,[X,Y]=( ),(x.y)=( ).
数学计算(x²-y²)(x+y)÷(x+y)²A.x-y B.x+y C.x²+y² D.x²-y²
化简x²/(y-x)-y²/(y-x)的结果是要求写具体过程、A -x-y B y-x C x-y D x+y.
Y>0则X、X-Y、X+Y选则A、X+Y最大,X-y最小B、X+Y最大X最小C、X最大X-y最小D、X-y最大X+y最小.
(x+y)-(a-b)(x+y)因式分解
因式分解 a(y-x)-b(x-y)
若(-x+y)·A=x²+y²,则A等于 过程最好清晰A.-x-y B.-x+y C.x-y D.x+y
(5)a(x+y)-b(x+y)-x-y因式分解
通分:-x/a(x-y) ,y/b(y-x)
通分x/a(x-y),y/b(y-x)
通分 a/(y-x)^2,b/(x-y)(x+y)
因式分解a(x-y)+b(y-x)+(2x-y)
