(2m+n-p)(2m-n-p)等于什么(2m+n-p)(2m-n-p)等于什么(2m+n-p)(2m-n-p)等于什么(2m+n-p)(2m-n-p)=[(2m-p)+n][(2m-p)-n]=(2
(2m+n-p)(2m-n-p)等于什么
(2m+n-p)(2m-n-p)等于什么
(2m+n-p)(2m-n-p)等于什么
(2m+n-p)(2m-n-p)
=[(2m-p)+n][(2m-p)-n]
=(2m-p)²-n²
=4m²-4mp+p²-n²
对我的回答有不明白的可以追问!
(2m+n-p)(2m-n-p)
=(2m-p+n)(2m-p-n)
=（2m-p）²-n²
=4m²-4mp＋p²-n²
4m×m-4mp+n×n-p×p
=（2m-P）^2-n^2
(2m+n-p)(2m-n-p)等于什么
（m-2n-p)(m-2n+p)-(m+2n+p)(m+2n+p)
a(m-n)^p*(n-m)^q*(m-n)^q*(n-m)^p等于什么?
（m+n-p）^2 等于多少?
若 P=2m,m=2n,则m+p-n等于（）
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
(m+n)()[m-(n+p)]=2m-p括号里填什么符号
(m+n)()[m-(n+p)]=2m-p括号里填什么符号急啊
(m+n)()[m-(n+p)]=2m-p括号里填什么符号
化简(-m+2n-p)(-p-2n+m)
(2m+n-p)(2m-n+p)
（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)
16（2m-n)^p+2*[-4(2m-n)^p-1]等于多少?
