因式分解的题目怎么做

m³n+mn³mn 这道题 要怎么做 用因式分解

然后 分解因式 (m+2n)^2-(m+2n)

Answer 1

m³n+mn³mn
解:原式=m³n(1+mn)

(m+2n)²-(m+2n)
解:原式=(m+2n)(m+2n-1)

Answer 2

m³n+mn³mn = m^3n+m^2n^4 =m^2n(m+n^3)
(m+2n)^2-(m+2n) =(m+2n)(m+2n-1),(提公因式法)

Answer 3

m³n+mn³mn
=m^3n+m^2n^4
=m^2n(m+n^3)
(m+2n)^2-(m+2n)
=(m+2n)(m+2n-1)
