计算:4(m-1)^2+(2m+5)(5-2m)计算:4(m-1)^2+(2m+5)(5-2m)计算:4(m-1)^2+(2m+5)(5-2m)4(m-1)^2+(2m+5)(5-2m)=4(m-1)

计算:4(m-1)^2+(2m+5)(5-2m)
计算:4(m-1)^2+(2m+5)(5-2m)

计算:4(m-1)^2+(2m+5)(5-2m)
4(m-1)^2+(2m+5)(5-2m)
=4(m-1)^2-(2m+5)(2m-5)
=4m^2-8m+4-(4m^2-25)
=-8m+29

4(m-1)^2+(2m+5)(5-2m)
=4m^2-8m+4+25-4m^2
=-8m+29
