[(2m+n)^2+(2m+n)(2m-n)]/2m,其中m=3,n=1/2化简求值!
[(2m+n)^2+(2m+n)(2m-n)]/2m,其中m=3,n=1/2化简求值!
[(2m+n)^2+(2m+n)(2m-n)]/2m,其中m=3,n=1/2化简求值!
原式=[4m^2+4mn+n^2+4m^2-n^2]/(2m)
=(8m^2+4mn)/(2m)
=4m+2n
=4*3+2/2=13 .
13,
(2m n )• (2m n 2m~n)•1/2m= (2m n )•2=13
(1),(-m-n)(-m+n) (2),(-m+n)(m-n)
(m-2n)(-m-n)
2(m-n)²-m(m-n)
(m-n)(m+n)+(m+n)²-2m²
m-n+2n^2/(m+n)
(m-2n/n-m)-(n/m-n)=
mn(m-n)-m(n-m)²2m(m-n)(2n-m)求过程
计算m+2m/n-m + n/m-n - 2m/n-m
计算m+2n/n-m+n/m-n-2m/n-m
分式加减法:化简:2m/m-n-n/n-m+m+2n/n-m
计算2m-n/n-m+m/m-n+n/n-m
计算:2m-n/n-m+m/m-n+n/n-m
计算m+2n/n-m+n/m-n-2n/n-m
(m-n)+2n(m-n)(m-n)的平方+2n(m-n)因式分解
[(m+n)(m-n)-(m-n)²+2n(m-n)]÷4n
4m(m-m)-2n(n-m)
(n/m+n/2m^2)*4m/n^2
m/(m-n)^2-n/(n-m)^2
