【6(y-1)4-8(x-y)3】÷(x-y)3的值
你好
【6(y-x)^4-8(x-y)^3】÷(x-y)^3
=6(x-y)^4÷(x-y)^3-8(x-y)^3÷(x-y)^3
=6(x-y)-8
=6x-6y-8

祝学习进步!
把(x-y),(a+b)作为一个因式,合并同类项:3(x-y)-9(x-y)-8(x-y)+6(x-y)-1
已知x-y=1,y≠0,求{(x+2y)²+(2x+y)(x+4y)-3(x+y)(x-y)}÷y的值.
1/2x-(x+y/2x -x-y)÷(x+y)
[(2x+y)²-y(y+4x)-8x] ÷2x 其中x=2,y=-1
先化简再求值:-3(2x-y)-{7-〔6x+2y-(10x-8y)〕+x-2(3x-4y)}已知x=-1/5,y=-5
1.(-2a)³·b²÷(8a³b²) 2.-5x(2x²-3x+4)+4x³+15x3.(x²-2y²)(x+2y)-2xy(x-y)4.(x-y+z)(x-y-z)化简求值 [(x+y)(x-y)-(x+y)²-2y(x-2y)]÷(-2y),其中x=5,y=2003
已知X=11Y,(X-2)*3=Y,(X-4)*5=Y,(X-6)*7=Y,(X-8)*9=Y ,求X、Y各是多少?
[(x+3y)(x-3y)-(x-3y)²]÷6y
1.(x^3-x^2-4x+1)/(x^2-3x+2)-(x^3-2x^2-9x+21)/(x^2-5x+6)+(x^2-3x+8)/(x^2-4x+3)2.{(x^2)/(x-y)}*{y/(x+y)}-{(x^4y)/(x^4-y^4)}÷{(x^2/x^2+y^2)^2}
求这道计算题哪里出错.4x=-6y,等式两边都减去2x-3y,得4x-(2x-3y)=-6y-(2x-3y),所以 2x+3y=-3y-2x,两边都处以2x+3y,得(2x+3y )除以2x+3y=(-3y-2x )除以2x+3y,整理后得1=-1
[(x+2y)(x-2y)+4(x-y)²]÷6x
把6x(x-y)的平方+3(y-x)的立方分解因式我知道答案是6x(x-y)^2+3(y-x)^3=6x(x-y)^2-3(x-y)^3=3(x-y)^2[2x-(x-y)]=3(x-y)^2(x+y)可为什么=6x(x-y)^2-3(x-y)^3=3(x-y)^2[2x-(x-y)]
计算:[(x/y-y/x)÷(x+y)+x(1/y-1/x)]÷y分之1+x
解方程组:2X+Y=8 3X-Y=7 X=?Y=?快,1.{2X+Y=8 2.{5X-8Y=8 3.{4X+3Y=1 4.{2X=5(X+Y){3X-Y=7 {3X+4Y=7 {2X+Y=2 {3X-10(X+Y)=2X=?Y=?X=?Y=?X=?Y=?X=?Y=?
分解因式:3x(x-y)3-6y(y-x)
(x+y)(x+y)-4(x+y-1)
x(x+y)-y(3x-4y)因式分解.快.
先化简再求值 [(x-y)²+(x+y)(x-y)]÷2x,其中x=3,y=1
