(m^2-3m)^2-8(m^2-3m)-20 十字相乘,
(m^2-3m)^2-8(m^2-3m)-20 十字相乘,
(m^2-3m)^2-8(m^2-3m)-20 十字相乘,
解
(m²-3m)²-8(m²-3m)-20——将m²-3m看成一个整体
=[(m²-3m)-10][(m²-3m)+2]
=(m²-3m-10)(m²-3m+2)
=(m-5)(m+2)(m-2)(m-1)
m-2m-3m+4m-5m-6m+7m-8m-9m+...+2002m-2003m-2004m求m的值
(m^2-3m)^2-8(m^2-3m)-20 十字相乘,
(m^2+3m)^2-8(m^2+3m)-20
计算:m-2m-3m+4m-5m-6m+7m-8m-9m+...+2002m-2003m-2004m
m-2m-3m+4m-5m-6m+7m-8m-9m+.+2002m-2003m-2004m
计算:(m+3m+5m+...+2009m)-(2m+4m+6m+...+2008m)
(m+3m+5m+...+2009m)-(2m+4m+6m+...2008m)
(m+3m+5m+...+2014m)-(2m+4m+6m+...+2013m)
(m+3m+5m+...+2013m)-(2m+4m+6m+...+2012m)
(m+3m+5m+...+2015m)-(2m+4m+6m+...+2014m)=
计算:(m+3m+5m+...+2009m)-(2m+4m+6m+...+2010m)
m-2m-3m+4m-5m-6m+7m.2004m=?
(m+3m+5m.+2013m)-(2m+4m+6m+.+2012m)=?
计算(m^3)^4+m^10m^2+m*m^3*m^8
若(2+根号3)^^m=1,求m²-1/m+1-m²-m/根号m²-2m+1的值
(m+3m+5m+...+2009m)-(2m+4m+...+2008m)怎么算
合并同类项m-2m+3m-4m+5m-.+2011m-2012m
m+3m+5m+...+2011m-2m-4m-...-2010m等于多少?
