几道因式分解..4ab(a+b)^2-6a^2b(a+b)(x+y)^2(x-y)+(x+y)(x-y)^22a(a-3
分解因式1.x^2+y^2+2x+6y+10 2.(1-y)^3+4(y-x) 3.(a-c)^2-4(a-b)(b-c
(2x+y)(2x-3y)+x(2y+y) 2a(x-y)-4b(x-y)
分解因式1.2a(x-y)-3b(y-x)2.-x^y-2xy+35y3.a^(x-y)-4b^(x-y)若|a+2|+
设A=2x-3xy+y+x-3y,B=4x-6xy+2y+4x-y,若|x-3a|+(y+3)=0,且B-2A=a.求A
已知a、b互为相反数,c、d互为倒数,X=4(a-2)-(a-3b),y=c²d-(cd+c-1),解x+y/
