初一数学因式分解

3，初中因式分解急

原式=[a+(a+1)]^2-a^2*(a+1)^2 =(2a+1)^2-(a^2+a)^2 =(2a+1+a^2+a)(2a+1-a^2-a) =-(a^2+3a+1)(a^2-a-1) 静下心来慢慢想就可以作出！
原式=[a+(a+1)]^2-a^2*(a+1)^2 =(2a+1)^2-(a^2+a)^2 =(2a+1+a^2+a)(2a+1-a^2-a) =-(a^2+3a+1)(a^2-a-1)

a(a+b+1)-a^3-ab^2 =a^2+ab+a-a^3-ab^2 =a(a+b)-a^2(a+b) =(a+b)(a-a^2) =a(a+b)(1-a).
你这么懒惰啊...全部用十字相乘法啊和求根公式.给你举几个例子算了...大同小异1.(x-2)(x-13)2.(x-1)(x-26)3.(x-2)(x-10)4.(x+20)(x-1)5.(x-20)(x-1)...
