(3m+2n+2)(2-3m-2n)方法步骤
(3m+2n+2)(2-3m-2n)方法步骤
(3m+2n+2)(2-3m-2n)方法步骤
用平方差公式,(3n+2n+2)(2-3m-2n)=((2+(3m+2n))(2-(3m+2n))=4-(3m+2n)^2=4-9m^2-12mn-4n^2
[(m-n)^2*(m-n)^3]^2/(m-n)^4
[(m-n)^2*(m-n)^3]^2/(m-n)^4
3m(m-n)-2n(m-n)的平方
因式分解(n-m)^3(m-n)^2-(m-n)^5
(m-n)2(n-m)3(n-m)4化简
(n-m)^3×(m-n)^2-(m-n)^5
计算(m+n)^3-(n+m)(m-n)^2
(m-n)^3(n-m)^2(m-n)=_____
4m(m-n)^2+4n(n-m)^3
2(m-n)的2次-(m+n)(m-2n)-3n(n-m)
2m-3n-m+2n
(m-n)3-(2n-m)3
(3m-n)(m-2n)=()
(m+2n)(m-3n)
(m-3n)(2m+n)
约分(m-n)^2/(n-m)^3
{(m+n)/2-(m-n)/2=1 (m+1)/3-(m-n)=-1 两种方法
{(m+n)/2-(m-n)/2=1 (m+1)/3-(m-n)=-1 两种方法
