(x+y)(a+2b)
(x+y)(a+2b)
(x+y)(a+2b)
=xa+2bx+ya+2yb
(x+y)²+2(y-x) 因式分解 怎么弄 我这还有几道题(x+y)²-(x+y)(x-z)+(x+y)(y+z)X(X-a)(x-b)-y(a-x)(b-x)x(x+y)(x-y)-x(x+y)²(2a+b)(2a-3b)-3b(2a+b)(a+b)²-9(a-b)²(a²+b²)²-a²b²9(x-y)-y&
(x+y)(a+2b)
(2a+b)(2a-3b)+3a(2a+b)和x(x+y)(x-y)-x(x+y)²4a(x+y)-6x-6y和啊a(a-b)-ab+b²
已知实数a,b,x,y,满足不等式(a+b)(x+y)>2(ay+bx),求证(x-y)/(a-b)+(a-b)/(x-y)>=2
因式分解,(a-b)(x-y)-(b-a)(x-y)(a-b)(x-y)-(b-a)(x+y)
3x(a-b)+2y(b-a)
9x^2(a-b)+y^2(b-a)
因式分解:(1)、(2a-3b)(7x+y)+(x-5y)(3b-2a)(2)、(x+y)^3(x+y)^2-(-x-y)
1.x(x-y)+y(y-x)2.9(a-b)^2-16(a+b)^2 3.25(x-y)^2+10(y-x)+1
(x-A)*(B-y)=x^2-9xy+8y^2,求A,B
因式分解:x^2y^2-4x a(a-b)-2b(b-a)
(a-b)+(-2a-b)=?(x+y-z)+(x-y+z)-(x-y-z)=?
设集合A={(x,y)|y≥|x-2|,x>=0},B ={(x,y)|y
已知有理数A,B,X,Y满足A+B ≠0,且(A+B):(A-B)=(2X+Y):(X-y) 那么A:(A+B)=?A.3X:(2X+Y) B.3X:(4X+2Y)C.X:(X+Y)D.2X:(2X+Y)
[1]a(x-2y)-b(2y-x)+d(2x-4y) [2]x平方-2xy+y平方-2x+2y+1 【3】一(a-x)(a-y)-x(y-a)(X-a)[1]a(x-2y)-b(2y-x)+d(2x-4y) [2]x平方-2xy+y平方-2x+2y+1【3】一(a-x)(a-y)-x(y-a)(X-a) 分解因式,急求!
如何解因式分解x(x-y)(a-b)-y(y-x)(b-a)
两个数学计算.a/b-(a-b)/b=x^2+xy/(x-y)÷xy/(x-y)
(1)2x(x+y)-4(x+y)^2.(2)(x+y)(b-a)+(x-y)(a-b)的分解因式解答过程
