(X-2y)(5a-3b)
因式分解:(1)、(2a-3b)(7x+y)+(x-5y)(3b-2a)(2)、(x+y)^3(x+y)^2-(-x-y)
x+y-(2x-y)(x+y)=?12(a^2-b^2)^2-3(a^2+b^2)(a+b)^2等于多少(2a-b)(2a+3b)+3a(b-2a)=-(2a-b)( ),a(x-3)(5-x)+b(3-x)(x-5)=( )(x-3)(a+b)代数式15x^3y^3(x-y),6x^2y^2(y-x),-120x^3y^3(x-y)(x+y)的公因式是?a-b+k(b-a)=( )(k-1)a(b-c)+c-b=(b-c)
(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&
定义a@b=2a-b求[(x+y)@(x-y)]@(x-2y)的值其中x=3y=5/2

(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
1,(x+y)²-(x+y),2,(x-y)²-(x-y)³2,(x-y)²-(y-x)³ 用分解公因式算(1).2(x-y)-3(y-x)²(2).4ad(a+b)²-6a²b(a+b)(3).(x+y)²(x-y)+(x+y)(x-y)²(4).2a(a-3)²-6a²(3-a)+8a(a-3)(5)2
1) (2x+5y)(2x-5y)(-4x^2-25y^2) 2) [(x+y)(x-y)-(x-y)^2+2y(x-y)]÷4y 3)整式乘除 3)(a+b)^2-2a(b+1)-a^2b÷ab 4)(a^2+3)(a-3)-a(a^2-2a-2)
3x(a-b)+2y(b-a)
(x+a)/2+(y-b)/3=a/2(x+a)/2-(y-b)=b/3(3x+2y)/4=(2x+y)/5=(x-y+1)/6
解下列关于x,y的方程组:(1){2x+3y=m,4x+5y=n (2){x/a+y/b=1,x/b+y/a=1 (|a|≠|b|≠0)
解下列关于x,y的方程组:(1){2x+3y=m,4x+5y=n (2){x/a+y/b=1,x/b+y/a=1 (|a|≠|b|≠0)

因式分解(2x+y)(5a+3b)
[(x-2y)²+(3x-2y)(3x+2y)]÷(-5x) (a-2b+3)(-a-2b-3).
(X-2y)(5a-3b)
[3(x+ y)^3-5(x+ y)^2-2x-2y]÷(x 还有一道,[(a+b)^3-2(a+b)^2+(a+b)]÷(a+b)
(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)?
