答案和解析
1/2(t-4)(4t-16)+1/2[（4t-16)+(t-1)]×3-1/2(t-1)(t-1)=
1/2(t-4)(4t-16)+3/2（4t-16)+3/2(t-1)-1/2(t-1)(t-1)=
1/2(4t-16)[(t-4)+3]+1/2(t-1)[3-(t-1)]=
1/2(4t-16)(t-1)+1/2(t-1)(4-t)=
4/2(t-4)(t-1)-1/2(t-1)(t-4)=
3/2(t-4)(t-1)
1/2(t-4)(4t-16)+3/2（4t-16)+3/2(t-1)-1/2(t-1)(t-1)=
1/2(4t-16)[(t-4)+3]+1/2(t-1)[3-(t-1)]=
1/2(4t-16)(t-1)+1/2(t-1)(4-t)=
4/2(t-4)(t-1)-1/2(t-1)(t-4)=
3/2(t-4)(t-1)
