(2x+3y)(a-b)-2(a-b)(x+y)如何化简
(2x+3y)(a-b)-2(a-b)(x+y)如何化简
(2x+3y)(a-b)-2(a-b)(x+y)如何化简
原式=(2x+3y)(a-b)-(a-b)(2x+2y)
=(a-b)(2x+3y-2x-2y)
=y(a-b)
=ya-yb
(2x+3y)(a-b)-2(a-b)(x+y)
=(a-b)*[(2x+3y)-2(x+y)]
=(a-b)*[y]
=y*(a-b)
(x+y)(a-2b)
因式分解x(a-b)^2+y(b-a)^3
3x(a-b)+2y(b-a)
3x(a-b)-2y(b-a)分解因式
(x+y)^2+2x+2y,(a-b)^3-2b(b-a)^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
已知:A=X*X-3xy+y*y,B=2x*x+xy-3y*3y.求A+B,A-B,A+2B
计算 1.[(a+b)^2-(a+b)(a-b)]÷(-b) 2.[(x+y)(2x+y)+(x+y)(x-y)]÷3x
a(x-3)(y-2)+b(3-x)(2-y)
x(y-x))^2(a-b)+(x-y)^3+(b-a)
(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&
(3x-y)(3x+y)+y(x+y);(a+1/2b)(a-1/2b)-(3a-2b)(3a+2b)快点,
因式分解:2a(x-y)-3b(y-x)
分解因式 3a(x+y)-2b(x+y)
(3x^/4y)^*2y/3y+x^2y^÷2y^/x 还有一个 (a+b/a-b)^*(2a-2b/3a+3b)-a^/a^-b^÷a/b
[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)
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)
通分 a/(y-x)^2,b/(x-y)(x+y)
