3(m+1)^2-5(m+1)(m-1)+2(m-1)^2,其中m=-5,求完全平方公式解答过程

m*m-5m-1=0则2m*m-5m+1/m*m 已知m＞4,化简|m-4|+|7-2m|+|m×m-2m+1|-|m×m-2m-3| 当m=1/2时,求15m²-9-{-4m²+[5m-8m²-(2m²-m)+9m²]-3m} [2m-1]²+5m[m-1]-[3m+1][3m-1] 化简 3(m+1)平方-5(m+1)(m-1)+2m(m-1)化简,求值 [(m-3)/(m+5)]^2+[(4-2m)/(m+5)]^2=1,求m 当m= 时,2m(3m-5)+3m(1-2m)=14 化简：(m-1)+2(m²-3m)-(2-m+5m²) m(m+1)(m+2)(m+3)+1? 化简|6-m|-|2m+1|+|m+5| (m 1/m(m+1)+1/(m+1)(m+2)+1/(m+2)(m+3)+.+1/(m+9)(m+10) 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) 计算：1/m(m+1)+1/(m+1)(m+2)+1/(m+2)(m+3)+1/(m+3)(m+4)+1/(m+4)(m+5)+.+1/(m+9)(m+10) 若多项式5x*x-2mxy-3y*y+4xy-3x+1中不含xy项,求（-（m*m*m）+2（m*m）-m+1）-（m*m*m+2m*m-m+4） 3m-1)(m+1)+(2m-1)(m-1)-(3m+5)(m-2)怎么计算? 化简3(m+1)^2-5(m-1)(m+1)+2m(m-1),其中m=3 已知m^2-5m+1=0,求m^3+1/m^3 和m-1/m的值
