2a+(x+y)-2(a+b)(化简)2a+(x+y)-2(a+b)(化简)2a+(x+y)-2(a+b)(化简)2a+(x+y)-2(a+b)=2a+x+y-(2a+2b)=2a+x+y-2a-2b
2a+(x+y)-2(a+b)(化简)
2a+(x+y)-2(a+b)(化简)
2a+(x+y)-2(a+b)(化简)
2a+(x+y)-2(a+b)
=2a+x+y-(2a+2b)
=2a+x+y-2a-2b
=x+y-2b
天天开心!
2a+(x+y)-2(a+b)
=2a+x+y-(2a+2b)
=2a+x+y-2a-2b
=x+y-2b
2a+(x+y)-2(a+b)
=2a+x+y-2a-2b
=x+y-2b

(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
9x^2(a-b)+y^2(b-a)
3x(a-b)+2y(b-a)
(x+y)(a+2b)
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
通分 a/(y-x)^2,b/(x-y)(x+y)
因式分解a(x-y)+b(y-x)+(2x-y)
(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&
因式分解:x^2y^2-4x a(a-b)-2b(b-a)
将(2x十3y)(a-b)-2(a-b)(x-y)化简
化简?(x+y)(a+b)-(x-y)(2a+b) 不全部拆开如何化简?
化简:2(x-3y)-3(2x-y) (8a-7b)-2(2a-3b) 2a-[a+(2a-2)]
(x-A)*(B-y)=x^2-9xy+8y^2,求A,B
对于有理数a,b.定义a*b=3a+2b.化简{(X+y)*(X-Y)}*(3X)
