㎡-4m+2=0
㎡-4m+2=0
㎡-4m+2=0
m²-4m+4=-2+4
(m-2)²=2
m-2=±√2
m1=√2+2,m2=2-√2
可转化为(m-2)^2=2解得m=2+正负根2,公式不好打中文代替了,希望可以帮到你
m^2-4m+4-2=0
(m-2)^2=2
m-2=±√2
m=2±√2
已知m×m+m-2=0,求m×m×m+3×m×m+2000的值
6√(3-4m)-3㎡√(3-4m)-8m√(3-4m)-9m+12㎡+2m^3=0
已知m*m+m-1=0,求m*m*m+2m*m-2005
m*m-5m-1=0则2m*m-5m+1/m*m
(m+3m+5m+...+2015m)-(2m+4m+6m+...+2014m)=
m-2m-3m+4m-5m-6m+7m.2004m=?
(m+3m+5m.+2013m)-(2m+4m+6m+.+2012m)=?
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
已知m^2+m-1=0,那么m^4+2m^3-m-2009=
m²-2m-4=0,则m³-m²-6m+2008=
㎡-4m+2=0
若(m-3)x^2*|m|-5-4m=0是关于x的一元一次方程,求m^2-2m+1/m的值
m=-1时,-2㎡-【-4m+(-m)】=?
(-0.5㎡+7/3m)(-4/3m+4)=5/3m(3-m)
(2m/m+2-m/m-2)÷m/m∧2-4
(2m+3)²= 2(4m+7)怎么化解成4m²+4m-5=0
m^3-4m^2+16m+192=0
已知sin&=m-3/m+5,cos&=4-2m/m+5(pi/2
