(m+n)^2+4m+4n+4m^2如何分解因式
(m+n)^2+4m+4n+4m^2如何分解因式
(m+n)^2+4m+4n+4m^2如何分解因式
(m+n)^2+4m+4n+4m^2
=5m^2+(4+2n)m+(n^2+4n)
令5m^2+(4+2n)m+(n^2+4n)=0
△=(4+2n)^2-4*5*(n^2+4n)= -16n^2-64n+16
m= [-(4+2n)±√△]/10
所以
(m+n)^2+4m+4n+4m^2
=5(m+((n+2+2√(-n^2-4n+1))/5)*(m+((n+2)-2√(-n^2-4n+1))/5)
(4m+2)(2m+4n)如何化成4(2m+n)(m+2n)?
[(m+n)(m-n)-(m-n)²+2n(m-n)]÷4n
4m(m-m)-2n(n-m)
因式分解4m^2(m-n)+4n(n-m)
4m(m-n)^2+4n(n-m)^3
(n/m+n/2m^2)*4m/n^2
[(m-n)^2*(m-n)^3]^2/(m-n)^4
[(m-n)^2*(m-n)^3]^2/(m-n)^4
4m^2(m+n)-9n^2(m+n)
(m-n)2(n-m)3(n-m)4化简
(m-n)^2*(m-n)^4=?
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3m=4n,则m/m+n+n/m-n-m^2/m^2-n^2=
m+n/4m^-n^-m-2m/n^-4m^=
(m-2n)(2n+m)-(-3m-4n)(4n-3m)=
(3m-4n)(4n+3m)-(2m-n)(2m+n)
[2(m+n)^5-3(m+n)^4+(-m-n)^3]÷[2(m+n)^3]
计算(m+4n)(m-n)-6(m+2n)(m-3n)
