4(m+1)^2-(1+2m)(2m-1)4(m+1)^2-(1+2m)(2m-1)4(m+1)^2-(1+2m)(2m-1)4(m+1)^2-(1+2m)(2m-1)=4(m^2+2m+1)-(4m
4(m+1)^2-(1+2m)(2m-1)
4(m+1)^2-(1+2m)(2m-1)
4(m+1)^2-(1+2m)(2m-1)
4(m+1)^2-(1+2m)(2m-1)
=4(m^2+2m+1)-(4m^2-1)
=4m^2+8m+4-4m^2+1
=8m+5
直接开出来。
4乘(m的平方+2m加1)-4m的平方-1。在开括号得出结果8m+3
已知m>4,化简|m-4|+|7-2m|+|m×m-2m+1|-|m×m-2m-3|
m*m-5m-1=0则2m*m-5m+1/m*m
已知m*m+m-1=0,求m*m*m+2m*m-2005
4m(m的平方-2m-1)+m(2m+5)(5-2m)
m*m-2m等于1,则2m*m-4m+2012
计算M-M^2/M^2-1*M-1/M除以(M-1/M+1)^2
解方程 2m-m*m 1=2(m*m-2m)(m*m-2m)
因式分解m^2(m+1)-(m-1)
m^2(m+1)-m-1 因式分解
化简|m|+|m-1|+|m-2|
已知m>4,化简:|m-4|+|7-2m|+|m^2-2m+1|-|m^2-2m-3|
化简,:3(m-1)^2+(m+2)(m^2-2m+4)-m(m^2+3m-3)
计算2m+6/m²-4m+4·1/m+3·(m-2)(m+3)/m+3
化简:m+|(1+m^2-2m)/(m-1)|
(m+1)(m+2)(m-1)(m-2)怎么计算?
(m+2/m^2-2m)-(m-1)/(m^2-4m+4)除以m-1/m,其中m=4
已知m-1/m=3,m不等于0,求m^2-1/m^2,m^3-1/m^3,m^4-1/m^4
分式m-m^2分之m^2-2m+1
