因式分解(分解因式)Factorization，把一个多项式化为几个最简整式的积的形式，这种变形叫做把这个多项式因式分解，也叫作分解因式。因为A^2-B^2=(A+B)(A-B) 还能分所以不时正确结果
应该不能作因式分解，因为(a+b)^3 及(a-b)^3本身已经是一个乘式了，它们只能作展开。 展开过程： (a+b)^3 =(a+b)×(a+b)^2 =(a+b)(a^2+2ab+b^2) =a(a^2+2ab+b^2)+b(a^2+2ab+b^2) =a×a^2+a×2ab+a×b^2+b×a^2+b×2ab+b×b^2 =a^3+2a^2b+ab...
结果1 题目 把一个多项式化成几个整式的积的形式,这种变形叫做因式分解 (factorization).例如, a^3-a=a(a+1)(a-1) , am+bm+cm =m(a+b+c), x^2+2x+1=(x+1)^2 都是因式分解.因式分解也可称为分解因式. 相关知识点: 试题来源: 解析 答案见上 反馈 收藏 ...
