（m-2n-p)(m-2n+p)-(m+2n+p)(m+2n+p)
（m-2n-p)(m-2n+p)-(m+2n+p)(m+2n+p)
（m-2n-p)(m-2n+p)-(m+2n+p)(m+2n+p)
（m-2n-p)(m-2n+p)-(m+2n+p)(m+2n+p)
=[（m-2n）-p][(m-2n)+p]-[(m+2n)+p][(m+2n) +p]
=(m-2n)^2-p^2-(m+2n)^2-2(m+2n)p-p^2
=-8mn-2(m+2n)p-2p^2
=-8mn-2mp-4np-2p^2
=-2(p+m)(p+2n)-4mn
（m-2n-p)(m-2n+p)-(m+2n+p)(m+2n+p)
=（m-2n)*（m-2n)-p*p-[（m+2n)*（m+2n)+2（m+2n)*p+p*p]
=m*m+4n*n-4mn-p*p-m*m-4n*n-4mn-p*p-2（m+2n)*p
=-8mn-2(m+2n)*p
（m-2n-p)(m-2n+p)-(m+2n+p)(m+2n+p)
化简,1.[(m+n-p)(m+p+n)-(m+n)²]/(-p),2.[(m+n)(m-n)-(m-n)²+2n(m-n)]/4n
化简(-m+2n-p)(-p-2n+m)
(2m+n-p)(2m-n+p)
(2m+n-p)(2m-n-p)等于什么
（2m+n-p）（ 2m+p-n）
(m-2n-p)(-m-2n-p)
化简:(2m+n-p)*(2m-n+p)
(-2m-3n-p)(2m-3n-p)
(m-2n+3p)(m+3n+3p)
因式分解：(m-n)(p-q)-(n-m)^2(q-p)
(2m+n-p)²
m-（2m-n-p）=
（m+n)-( )=2m-p
(m-n)(p-q)(p+2q)-(n-m)(p+q)(p+2q)
n/m与2n+q/m+p,怎么通分
已知m,n,p都是整数,且|m-n|的三次方+(p-m)的二次方=1,则|p-m| +|m-n|+2|n-p|=
已知m,n,p都是整数,且,|m-n|的3次方+|p+m|的五次方=1则|p-m|+|m-n|+2|n-p|= .
