3x(a-b)-6y-(b-a)解算3x(a-b)-6y-(b-a)的详细解算步骤？

（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 3a(x-y)-6b(y-x) 3a(x-y)-6b(y-x) 分解因式6a[x-y]-3b[y-x] 3x(a-b)-6y(b-a) 初一因式分解练习题,谁好心帮我解下表示平方1.2X~-3XY-X2.(X+Y)~(X+Y)(X-Y)(X+Y)(Y+Z)3.3X(a+2b)~-6XY(a+2b)4.a(x-y)-b(X-Y)-C(Y-X)5.(b-a)~-2a+2b6.(x-y)~-m(y-x)+y-x7.x(x-y)(a-b)-y(y-x)(b-a)8.已知a+b=13,ab=40,求 b+ab~的值 因式分解 (1)6(x-y)^3-3y(y-x)^2 (2)x(x-y)(a-b)-y(y-x)(因式分解(1)6(x-y)^3-3y(y-x)^2(2)x(x-y)(a-b)-y(y-x)(b-a)(3)(a+b)(a+b-1)-a-b+1 3x(a-b)-6y-(b-a)解算3x(a-b)-6y-(b-a)的详细解算步骤？ 化简；6（a-b)(x-y)²-3(b-a)(x-y)^4 已知x-y=6,a+b=-3则(a+y)-(x-b)= 2x/x+y+2y/x+y a/a+b+b/a-b 1/3x²+2/4y-5/6xy解出来快 集合A={(x,y)|x-2y=1}B={(x,y)|x+3y=6},则A∩B= A∪B=? A=｛x|y=-4x+6｝,B=｛x|y=5x-3｝,求A∩B. 几道 数学题急啊 对了再加20分(x+y)^2-(x+y)^3(x-y)^2-(x-y)^3 (x-y)^2-(y-x)^32(x-y)-3(y-x)^24ab(a+b)^2-6a^2b(a+b)(x+y)(x-y)-(x+y)^28a(x-y)^2-4b(y-x)a=-5 a+b+c=-5.2求代数式a^2(-b-c)-3.2a(c+b)的值 已知集合A={y|y=x*x-6x+5},B={y|y=6x+3-9x*x}求A交B A=｛y|y=-4x+6｝,B=｛x|y=5x-3｝,求A∩B. 十字相乘法分解因式(只要答案) x*x-2x-1 x*x-2ax-3a*a a*a*a-b*b*b x*x+x-(y*y+y)x*x-2x-1 x*x-2ax-3a*a a*a*a-b*b*b x*x+x-(y*y+y) (1).
