m^2n^2-1/4(m^2+n^2)^2 因式分解xiexie
先把括号打开(不要害怕那个四次方)
原式=-1/4(m^4+2m^n^2 +n^4-4m^2n^2)
=-1/4(m^4-2m^2n^2+n^4)
=-1/4(m^2-n^2)^2
(1),(-m-n)(-m+n) (2),(-m+n)(m-n)
[(m+n)(m-n)-(m-n)²+2n(m-n)]÷4n
(m-2n)(-m-n)
(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)
因式分解4m^2(m-n)+4n(n-m)
4m(m-n)^2+4n(n-m)^3
(m-n)2(n-m)3(n-m)4化简
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)^2*(m-n)^4=?
因式分解m^2-(n+1)m+n
m-n+2n^2/(m+n)
4m(m-m)-2n(n-m)
(m-2n/n-m)-(n/m-n)=
2(m-n)²-m(m-n)
(m-n)(m+n)+(m+n)²-2m²
