1 A(a-b+c)-bc
2 2a(x-5y)+b(5y-x)
=-(2b+b)(x-5y)
3 3x(a+b)+4y(a+b)
=(3x+4y)(a+b) 我说兄弟 在没在看啊?在看就回一句话.这太多了 别让我白打啊
你要看我的 我就接着打
（a+c)(a-b)
(2a-b)(x-5y)
(3x+4y)(a+b)
(m-n)(m+5)
(x+y)(x-y+a)
(a-b-c)(a-b+c)
(x-y)(x+y)^2
(2a-b)(2a+b+3)
(3m-n)(3m+n-2)
(x-y+z)(x+y-z)
(x+y)(x-y)^2
给分啊大哥
依次来：（a-b）（a+c）;
(2a-b)(x-5y);
(a+b)(3x+4y);
(m+5)(m-n)=m²+5m-mn-5n
(x+y)(x-y+a)=x²-y²+ax+ay
(a-b)^2-c^2=a²-2ab+b²-c²
我已经尽力了
