(2m+2)*()=4n^2-m^2括号里填什么不是(2n+m)(2n-m)吧!
(2m+2)*()=4n^2-m^2括号里填什么
不是(2n+m)(2n-m)吧!
(2m+2)*()=4n^2-m^2括号里填什么不是(2n+m)(2n-m)吧!
不是(2n+m)(2n-m)
应该填 {[(2n+m)(2n-m)]/(2m+2)} 或[(4n^2-m^2)/(2m+2)]
(m-n)-2(m+2n)=?去括号
m-[n-2m-( )]=4n-2m 括号里应填,急
代数式 括号n-3(4-2m)
去括号的2m-{n+[4m-3(m+2n)+6m]-5m} m=3分之2 n=-4
(m+n)-( )=2m-p括号里应填什么
(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
(m-n)^2*(m-n)^4=?
已知3m=4n,则m/m+n+n/m-n-m^2/m^2-n^2=
(2m+2)*()=4n^2-m^2括号里填什么不是(2n+m)(2n-m)吧!
m+n/4m^-n^-m-2m/n^-4m^=
(m-2n/n-m)-(n/m-n)=
(m-2n)(2n+m)-(-3m-4n)(4n-3m)=
4m(m-m)-2n(n-m)
去括号:n一3(4-2m)
n-3(4-2m)怎么去括号
.4(m+n)^2*(m+n)^3-7(m+n)(m+n)^4+5(m+n)^5=
