(m-2n)(2n+m)-(3m-4n)² 怎样化简?
(m-2n)(2n+m)-(3m-4n)² 怎样化简?
(m-2n)(2n+m)-(3m-4n)² 怎样化简?
伸手能碰到天,
(m-2n)(2n+m)-(3m-4n)²
=m²-4n²-9m²-16n²+24mn
=-8m²-20n²+24mn
=-4(2m²-6mn+5n²)
(3m-4n)(4n+3m)-(2m-n)(2m+n)
2(m-n)^2-(m+n)(m-2n)-3n(n-m) 公因式(n-m)
m/n=5/3,求(m/m+n)+(m/m+n)-(n^2/m^2-n^2)
已知m/n=5、,求(m/(m+n))+(m/(m-n))-(n^2/(m^3-n^2))
(m+2n)(2m+n)-(3m-n)(m+2n)
计算(3-m+n)*(3+m-n)-(2-m+n)*(2+m-n)
(m-n)m立方;+2n(n-m)平方
1/(m-n)-1/(m+n)-2n/(m^2+n^2)-4n^3/m^4+n^4)-8n^7/(m^8+n^8)-16n^15/(m^16+n^16)+32n^31/(n32-m32)
因式分解:(m+n)^3+2m(m+n)^2+m^2(m+n)
【(m+n)(m-n)-(m-n²)+2n(m-n)】÷4n
(4(m-n)^3)/((n-m)^2)
lm+n-3l+m^2n^2+4mn+4=0 求(4m-n)(m-2n)-(n-m)(-m-n)
(5m+2n)(5m-2n)-(3m-4n)(4m+3n)
2m(m-n)^2-4n(n-m)^3 (分解因式)-7m(m-n)^3+21mn(n-m)^2 (分解因式)快
若5m-3n=-4,求出2(m-n)+4(2m-n)
2m-{n+[4m-3(m+2n)]}-5n化简求值
m-{n-2m+[3m-(6m+3n)-5n]}化简
已知|2m-n/m+2n|=3,求2(2m-n)/m+2n-2m-n/m+2n-3的值
