(2x-3y)(a+b)+(3x-2y)(a+b)提公因式后等于是等于(a+b)(5x-5y)还是5(a+b)(x-y)?
(2x-3y)(a+b)+(3x-2y)(a+b)提公因式后等于
是等于(a+b)(5x-5y)还是5(a+b)(x-y)?
(2x-3y)(a+b)+(3x-2y)(a+b)提公因式后等于是等于(a+b)(5x-5y)还是5(a+b)(x-y)?
这里是提两次公因式
第一次是(a+b)(5x-5y)
第二次是5(a+b)(x-y)
(2x+y)(2x-3y)+x(2y+y) 2a(x-y)-4b(x-y)
因式分解:a(x-y)^2+b(y-x)^3 4(x-y)^2+8(y-x)(x+y)1.a(x-y)^2+b(y-x)^3 2.4(x-y)^2+8(y-x)(x+y)
a(x-3)(y-2)+b(3-x)(2-y)
因式分解:2a(x-y)-3b(y-x)
分解因式 3a(x+y)-2b(x+y)
因式分解:(x+y)^3(x-y)-(x+y)(x-y)^3,9x^2-16(a+b)^2
(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 (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
a/x-y,b/3y-3x,c/x^2-2xy+y^2通分
x+y=a,x-y=b.求2x-3y等于
通分 a/(y-x)^2,b/(x-y)(x+y)
因式分解a(x-y)+b(y-x)+(2x-y)
A={(x,y)|y=-x^2+mx-1},B={(x,y)|y=3-x,0A={(x,y)|y=-x^2+mx-1},B={(x,y)|y=3-x,0
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
计算 1.[(a+b)^2-(a+b)(a-b)]÷(-b) 2.[(x+y)(2x+y)+(x+y)(x-y)]÷3x
已知3x+2y=a,2x+3y=b,则(x+y)(x-y)=?
方程组:3(x+y)-a(x-y)=16,2(x+y)+b(x-y)=15的解是什么?
集合A={(x,y)|y=-x^2+mx-1},B={(x,y)|y=3-x,0
