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 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|. 化简(-m+2n-p)(-p-2n+m) 化简:(2m+n-p)*(2m-n+p) （m-2n-p)(m-2n+p)-(m+2n+p)(m+2n+p) 已知m、n、p满足/2m/+m=0,/n/=n,p/p/=1,化简/n/-/m-p-1/-/2n+1/. a(m-n)^p*(n-m)^q*(m-n)^q*(n-m)^p等于什么? (m-n+p)(m+n-p)等于多少 (m-2n+3p)(m+3n+3p) (m+n)(p+q)-(m+n)(p-q) (3m-n-p)(3m+n-P) (2m+n-p)(2m-n+p) (2m+n-p)(2m-n-p)等于什么 （2m+n-p）（ 2m+p-n） (3m+n-p)(3m-n+p) 计算(-3m+n-p)(3m-n-p) (m+n+p-q)(m-n-p-q) 怎么算 (m-2n-p)(-m-2n-p)
