1个回答
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)
(2m+n-p)( 2m+p-n)
下列变形中错误的是( ) A.m 2 -(2m-n-p)=m 2 -2m+n+p B.m-n+p-q=m-(n+p-q
已知m,n,p满足|2m|+m=0,|n|=n,p•|p|=1,化简|n|-|m-p-1|+|p+n|-|2n+1|.
已知m、n、p满足|2m|+m=0,|n|=n,p|p|=1.化简:|n|-|m-p-1|+|p+n|-|2n+1|.
计算:(2m+n-p)(2m-n+p)
化简(m+2n-3p)2-(m-2p)(m-n)
已知m,n,p都是整数,且|m-n|+|p-m|=1,则|p-m|+|m-n|+3(n-p)2=______.
